The top and bottom glass can also be patterned with various layers of conducting materials and thin film transistors that allow the voltage across the liquid crystal cells to be varied to manipulate the orientation of the liquid crystal, thereby controlling the color and brightness of the pixel. During display updates, the circuit can function as in a standard LCD display. DE DET5 en The relationship between the drive signal and the signal appearing on sense lines b can be a function of the capacitance coupling the drive and sense lines, which, as noted above, may be affected by an object in proximity to node Because the system can scan the touch pixels in any desired pattern, a scan pattern can be designed that ensures that adjacent rows and adjacent pixels are never driven at the same time, thereby avoiding fringe field interaction that can result in signal loss or a lower signal-to-noise ratio. By upside down, it is meant that the user surface of the device is the bottom surface not shown.

V STM Effects V STM modulation, under certain conditions, can have a negative impact on the voltages of the subpixels underneath the touch drive motogola being modulated.

Replacing Patterned ITO with Metal Various embodiments can eliminate the patterned ITO layer that forms touch sense electrodes and replace this layer with very then metal lines deposited on one of the layers, for example, on the top glass. A set of drive and sense lines can be motoropa horizontally from bus linesat the sides of the display to each individual touch pixel One such alternative method is disclosed in J.

As shown in the display stackup of FIG. If necessary, lower effective resistance for ITO 3 can be achieved by adding metal traces that run parallel to the touch cp segments.

It may also be desirable for image quality reasons to separate the active touch drive segment farther away from the area of the display being updated.

Concept G One issue that can arise in an IPS-based touch-sensing display is that a lack of 60.9.06 between the touch and the LC means a finger or other touch object can affect the display output. Display device can also include an integral touch screen shown separately for clarity, but actually integral with the display that can be operatively coupled to the processor For purposes of reference herein, the sides will be referred to as north, south, east, and west as indicated in the drawing.

Starting at the top, touch sense electrodescan be deposited on the top user side of LCD top glass The manufacturing of LCD panels can be done jotorola a batch process on large pieces of glass called mother-glass.

This can provide several benefits, including: The large capacitance can be due to the thin e. The select traces connect to gate drive circuitry made up of poly-silicon thin film transistors p-Si TFTsalso not shown.

6.90.06 For handheld devices, the system processor board that manages the data and controls for the LCD can be placed under the backlight Multi-touch sensing arrangement can detect and monitor multiple touch attributes including, for example, identification, position, velocity, size, shape, and magnitude across .609.06 sensitive surfaceat the same time, nearly the same time, at different times, or over a period of time.

Program storage block can provide a place to mogorola data being used by computer system The microcontrollers may also be digital signal processors DSPs. Switches can be implemented as TFTs on glass. For example, a sensor IC may be used for all lines, or multiple sensor ICs may be used for a single line or group of lines.

Because providing touch stimulus may disturb the voltage across the LC, LCD pixel writing can take place just after the touch stimulus phase to reduce the time duration of any disturbance. Protective resist could also be used. Method and apparatus for indicating a change in status of an object and its disposition using animation.

The touch screen of claim 24wherein the display is oriented with the first substrate positioned nearer a user than the second substrate.

Touch drive from two sides can reduce the distortion of the LC pixel voltage. These switches can be implemented as TFTs on glass.

The area of the display currently being updated motodola should not overlap an active touch drive segment. However, any technology may be used depending on particular design constants. For example, a noise component may be added to the touch signal when one touch drive segment is being modulated with V COM at the same time another touch drive segment is being used for touch sensing. This can reduce noise and motorols the measured effect of touches to the display.

In some embodiments, the mmotorola pattern used in the touch elements may be optimized to reduce visual artifacts. This approach can have several benefits including, for example, eliminating CMOS in the peripheral area, which can reduce cost, and eliminating logic in the peripheral area, which can reduce power consumption.

Rather, while a portion of the display is being updated, another portion may be scanned for touch. In some embodiments it may be a sine wave of about 5V peak-to-peak with zero DC offset. FPC can also provide the substrate for various components supporting touch and LCD operation, and can also connect to the backlight FPC through two pads Display panel with touch detection function, drive circuit, and electronic device.
