The technical field to which the invention relates

The invention generally relates to a mobile electronic device having a capacitive sensor with zone isolation reduced visibility.

The level of technology

Mobile electronic devices such as cell phones, PDAs, MP3 players, traffic computers and the like, are very common computing devices. Electronic devices provide different characteristics, such as communication, computing characteristics, access to the Internet, play music and videos, view images, etc. Such electronic devices often will include a display device such as LCD (liquid crystal display, LCD).

One of the challenges associated with the integration of new features and functionality with devices like mobile phones, includes a user interface. Traditional mobile phones include only 12 to 15 buttons. Such devices are sometimes not compatible with the new features and functions, as new modes of operation that require new specialized buttons or input devices in addition to the basic phone buttons. In addition, the device also may require additional buttons for the purpose for which hacii or the introduction of new modes within the device.

One of the decisions regarding the need for more buttons in the user interface is to simply add additional keys in the device. Some devices, for example, include a full keyboard from forty to fifty buttons. The problem with this solution is that many mobile devices, including mobile phones become smaller and thinner. When many buttons there is a group in one location, the likelihood of confusion or difficulty of the user during operation of the device increases. Moreover, in a particular mode, many of the buttons are not needed. For example, when the device is in camera mode, the numeric keys 1-9 are usually not needed for photography.

As usual assigned in the process of simultaneous consideration of applications for the issuance of U.S. patent No. 11/684454 filed March 9, 2007, entitled "Adaptive Multimodal User Interface for a Portable Electronic Device", and 11/679228, filed February 27, 2007, entitled "Adaptable User Interface and Mechanism for a Portable Electronic Device", included in the materials of the present application by reference in its entirety, discloses a method and apparatus for providing a portable electronic device that hides and displays various configuration buttons the user through optionscom the shutter. The optical shutter configured to selective opening and closing of the shutter segments by applying an electric field, thereby hiding and showing the user the triggered objects. The above-defined optical shutter is a capacitive sensor configured to detect the presence of an object such as a finger of a user located near or touching any particular triggered the user interface object in the user interface area that is visible to the user through the transparent plastic cover of the device.

Capacitive sensor may include a layer of oxide of tin and indium (ITO), is selectively etched to create areas of ITO, which are electrically isolated from each other. The area where ITO was Vitrulan, known as the "zone of exclusion". One problem with this device is that the area of ITO reflect much more light than the isolation zone. When the device is in the off state, can be implied that it should create a uniform black or grey appearance. For example, the ITO layer can be printed on black or gray background to create a black or grey appearance. Despite the fact that most of the light passing through the capacitive sensor may pohlad the sterile black background additional light that is reflected from areas of the ITO, which may be objectionable in contrast to the black background that is visible through the isolation zone, making visible the structure of ITO. It was found that the area of ITO typically can have a four times greater reflectivity than the isolation zone.

Mobile electronic device includes a capacitive sensor having an electrode layer with newyrovdenyj areas and etched sections and having isolation zone is formed on the etched areas, and the segmented optical shutter, located on the side of the capacitive sensor, the optical shutter comprises a liquid crystal layer inserted between the upper absorbing polarizer and the lower absorbing polarizer, and includes an element of increasing reflectivity, located between the liquid crystal layer and the lower absorbent layer. The reflectivity of the element increase reflectivity is selected to reduce the relationship of reflectivity to levitralink sites to reflectivity on the etched areas to make the appearance of the user is Lyskovo interface essentially homogeneous in the off state.

DETAILED description of the INVENTION

Additional features and advantage of the tion of the invention will be set forth in the description, which should, and will in part obvious from the description or may be learned by carrying out the invention in practice. The characteristics and advantages of the invention may be realized and obtained by means of the instruments and combinations specified in detail in the attached claims. These and other features of the present invention will become more fully apparent from the following description and appended claims, or may be learned by practicing the invention in practice, as described in materials of this application.

Various embodiments of the invention are described in detail below. Although discussed some implementations, it should be clear that this is done for illustrative purposes only. Specialist in the relevant field of technology will recognize that other components and configurations can be used without leaving the nature and scope of the invention.

The invention contains a variety of embodiments, such as the method and the device, and other embodiments of which relate to the basic concepts of the invention. The invention may include transforming the keyboard, which performs hiding and opening functions by opening and closing valves in the element of the optical shutter. The optical element satw the RA acts as a segmented electro-optical device by reason of he selectively changes the polarization axis of light passing through the keyboard. When the electro-optical device is used in conjunction with layers of polarized light, change the axis of polarization causes a predefined gates to open or close, changing appearance, visible to the user.

Layers of polarized light absorb light polarized along the axis of polarization and transmit light polarized along the second axis of polarization. Despite the fact that some small amount of light polarized along the first axis, can be reflected, most of the light is absorbed by the polarizer. These polarizers therefore are usually gray or black in appearance when the light is absorbed. Thus, when all the optical shutters are closed, the surface of the device may have a grey or black appearance, and it would be advantageous if this appearance was homogeneous. The present invention provides essentially uniform appearance to the surface of the mobile electronic device, as further described below.

Figure 1 illustrates an exemplary diagram of the mobile electronic device 100 in accordance with a possible embodiment of the invention. Mobile electronic device may include a display 101 high resolution and segmented electrohop the ical display 102. The segmented electro-optical display 102 is configured as an optical shutter to imagine based on the dynamic keyboard 103 to the user. Based on the dynamic keyboard 103 can display one of many configurations of the keyboard and associated with the current operation mode of the electronic device 100. Based on the dynamic keyboard 103 and the configuration of the keyboard may include only those buttons that are necessary for navigating in a particular mode of the device.

In addition to the display 101 high resolution and segmented electro-optical display 102 of the exemplary electronic device 100, shown in figure 1, may also include device 104 navigation. The device 104 navigation can be used for selective navigation between the different modes of the device. The device 104 navigation can also be used as a management body for each mode of operation. The device 104 navigation can be continuously available to the user. Alternatively, the navigation device can selectively hide and display the segmented electro-optical display 102. The device 104 navigation, in the embodiment of figure 1, is located in region 106 of the keyboard of the electronic device is 100. This is a geometric location provides device 104 navigation can be large and easily accessible.

The display 101 high resolution may include liquid crystal display (LCD)configured to provide information about the device user. The term "display 101 high resolution" in the materials of this application is used to refer to a device that can render text and images to the user by changing a large number of pixels, which, when together are viewed by a user, form presents the text or image. The term "high resolution" in the materials of this application is used to mean a display suitable for presenting text information and graphics on a mobile device with sufficient granularity so as to easily switch between graphics or text. For example, high-resolution display would be suitable for presenting images to the user in the format of the joint group of experts on machine processing of photographic images (JPEG). Such displays are typically configured to turn on and off individual pixels via driver display for presenting information with high resolution. Examples include reflective the CD or LCD display with backlight 256-pixels by 128 pixels, while it can be the LCD of any size.

The front surface 105 of the electronic device 100 forms a complete user interface. In region 106 keyboard segmented electro-optical display 102 provides a dynamic interface for user input. This dynamic user interface configured to represent different indicators that can appear as the triggered objects, for example, around the user interface in area 106 of the keyboard.

Figure 2 illustrates a side view of the dynamic user interface 200, which may form an exemplary electronic device 100 in accordance with a variant embodiment of the invention. User interface 200 may include multiple layers. Although shown several layers, not all and every the layers may be needed for each application, and the structure shown is approximate. In addition, additional layers not shown could also be included in the user interface as needed, such as substrate layers and electrode layers.

The user interface 200 includes a segmented optical shutter 202 capacitive sensor layer 204 and 206 of the coating. The optical shutter 202 includes a bottom polarizer 208, the layer 210 DBF, the polarizer 212 low E, the liquid crystal material 214 and the upper polarizer 216. The lower polarizer 208 and the upper polarizer 216 can be absorbing polarizers. The optical shutter may also include a placeholder electrode (not shown), showing buttons or symbols, and the application of the electric field may be selectively forced to change the properties of the transmittance of liquid crystal material, thus causing selective opening and closing of Windows of the optical shutter to display the buttons as needed. For example, the music player mode may correspond to a first configuration, and the phone mode may correspond to an alternative configuration. The liquid crystal material 214 may be material twisted nematic liquid crystal (TNLC), although it can use other types of liquid crystal material. The layer 206 of the coating can be a thin plastic film, glass or other suitable material.

Capacitive sensor 204 is configured to detect the presence of an object such as a finger of a user located close to or touching the user interface 200. Detected capacitance change near the area to which the touch, and thus can be detected user selection creativus the x objects such as a button on the keyboard. Capacitive sensor can be formed from the electrode layer 218 and connecting layer 220. Electrode layer 218 may be oxides of tin and indium (ITO), for example, which erased to create areas of ITO, which are electrically isolated from each other. The area where ITO was Vitruvian are "zones of exclusion", as shown in the center of figure 2, between the two sections of electrode layers 218. Linking layer formed under the electrode layer 218 and between areas of the electrode layer 218 in the areas of isolation.

Electrode layer 218 and any underlying substrate can be layered on black or grey color to give a black or gray appearance of the device when it is in the off state. However, the electrode layer 218 reflects essentially more light than the isolation zone, which could lead to undesirable visible contrast between zones ITO and zone isolation. Embodiments of the present invention essentially eliminate this apparent contrast through the use of reflective polarizer 210. The reflective polarizer 210 may be DBEF (dual film image intensification), such as Vikuiti DBEF 3M. The reflective polarizer 210 transmits light of the first polarization and reflects light of another polarization.

The polarizer 212 low E is a polarizer low efficiency is productivity. The polarizer low E is an absorbing polarizer with a low efficiency of polarization relative to that of the polarizer full absorption, where the polarization efficiency is defined as the number of polarized light, the noise in the direction of the maximum transmittance of polarized light of the polarizer, divided by the number of polarized light, the noise in the direction of minimum transmittance of polarized light of the polarizer when the source of unpolarized light is projected through the polarizer. The polarizer low-E can be used to adjust the appearance of the user interface. In particular, without the use of a polarizer 212 low E reflective polarizer 210 may give silver or shiny appearance of the user interface. It may be desirable to have a user interface that has a gray appearance, which can be given to the inclusion of the polarizer 212 low E. the gray Level can be adjusted by selection of the polarizer low E with good efficiency. Embodiments of the invention can be used with a reflective polarizer 210 without the use of a polarizer 212 low E or can be used as a reflective polarizer 210 and the polarizer 212 low E. When COI is lesuuda both, the reflective polarizer 210 and the polarizer low E, you can choose a reflective polarizer with the proper amount of reflectivity and select the polarizer low E with efficiency to give the desired appearance.

Figure 3 is a graph illustrating the % reflectivity in the areas of insulation in comparison with ITO in configuration a, which is the structure of figure 2, without reflecting polarizer polarizer 210 and 212 of the low E, a and configuration B, which is the structure of figure 2, with reflective polarizer polarizer 210 and 212 low E. In the configuration of A reflectivity in % in zones ITO is a reflectivity of approximately 2%, along with the fact that in areas of isolation reflectivity in % has a value of approximately 0.5%. This is a consequence of the contrast between zones ITO and zone isolation 2/0,5, or 4:1, which creates undesirable visible contrast in appearance between zones ITO and zone isolation.

In configuration B, which is the structure of figure 2 with the reflecting polarizer polarizer 210 and 212 low E, reflectivity in % raised in the isolation zones and zones ITO approximately 25%. This results in a reflectivity in % in zones ITO approximately 27%, and in areas of isolation about 25.5%, which creates a contrast 27/25,5, of 1.05:1. This is is a consequence of the essentially invisible contrast between the isolation zones and zones ITO, resulting in essentially homogeneous gray or black appearance.

Figure 4 illustrates an exemplary block diagram of the sequence of operations of the production method of the mobile electronic device according to alternate embodiment of the invention. 4100 way begins. 4200 is a capacitive sensor having an electrode layer with newyrovdenyj areas and etched sections and having isolation zone is formed on the etched areas.

At 4300 segmented optical shutter is placed on the side of the capacitive sensor. The optical shutter comprises a liquid crystal layer inserted between the upper absorbing polarizer and the lower absorbing polarizer, and includes an element of increasing reflectivity, located between the liquid crystal layer and the upper absorbing polarizer.

On the 4400 is selected reflectivity of the element increase reflectivity to reduce the relationship of reflectivity to levitralink sites to reflectivity on the etched areas to make the appearance of the user interface is essentially homogeneous in the off state. At 4500 sequence of operations ends.
