摘要:
Methods and devices employing circuitry for quickly discharging pixels of a display before the display is turned off are provided. In one example, a method may include receiving at the electronic display a signal indicating the electronic display will be powered off within a period of time. The method may also include, in response to the signal, causing a frame of pixel data originating from the electronic display to be stored in pixels of the electronic display before the electronic display is powered off. Storing the frame of pixel data in the pixels may inhibit image artifacts from occurring on the electronic display when the electronic display is powered back on in the future.

Data can be written to a sub-pixel by applying a voltage to the sub-pixel's data line. A large change in voltage on a data line can affect the voltages on adjacent data lines due to capacitive coupling between data lines. The resulting change in voltage on these adjacent data lines can give rise to visual artifacts in the data lines' corresponding sub-pixels. Various embodiments of the present disclosure serve to prevent or reduce the appearance of these visual artifacts by inserting guard lines between data lines to reduce the mutual capacitance between data lines. In other embodiments, a pixel having multiple gate lines can be used to selectively turn on and turn off different sub-pixels which, in turn, can reduce or eliminate the appearance of visual artifacts.

A method and system is disclosed for powering device sub-circuitry of an electronic device. The sub-circuitry may be used to provide control signals to a direct current switcher on a main system board, thus eliminating passive circuitry typically associated with the sub-circuitry. Furthermore, by actively generating the control signals for the direct current switcher, explicit timing control circuitry is not required to synchronize the transmitted power to the sub-circuitry.

Systems, methods, and devices relating to directly bonding electrode pads of a flexible printed circuit (FPC) to electrode pads of a glass substrate are provided. In one example, such a system may include a glass substrate with electrode pads and an FPC with corresponding electrode pads. A joining edge of each electrode pad of the FPC may couple directly to a joining edge of a corresponding electrode pad of the glass substrate, without an intervening conductive adhesive layer or an anisotropic conductive film (ACF) layer, or a combination thereof.

Systems and methods for preventing parasitic capacitances within liquid crystal displays are provided. A display panel according to an embodiment may include, for example, a pixel with a pixel electrode and a transistor coupled to a gate line. Additionally, the pixel may include a shielding conductor interposed between the pixel electrode and the gate line. The shielding conductor may shield the pixel electrode from a parasitic capacitance with the gate line by causing a parasitic capacitance to form between the gate line and the shielding conductor instead of between the gate line and the pixel electrode.

Systems, methods, and devices are disclosed, including a device having a liquid-crystal display (LCD) panel that includes a transistor-degradation circuit. In some embodiments, the transistor-degradation circuit is configured to output a signal indicative of a change in a property of a transistor on the LCD panel over time.

Systems and methods for monitoring internal resistance of a display. The method may include supplying the display via a capacitor with a first voltage configured to enable the display to receive one or more touch inputs. After supplying the display with the first voltage, the method may include discharging the capacitor to a second voltage configured to enable the display to display image data. The method may then monitor a discharge waveform that corresponds to when the capacitor discharges from the first voltage to the second voltage. Based at least in part on the discharge waveform, the method may determine a chip on glass resistance value and a flex on glass resistance value that correspond to an internal resistance of the display.

An apparatus configured to create a resistive pathway for an electronic assembly is disclosed. In one embodiment, the pathway can be formed with a resistive film in conjunction with a conductive adhesive and a coverlay. In another embodiment, the resistive film, the conductive adhesive and the coverlay can be relatively transparent. In yet another embodiment, the resistive pathway can couple directly with traces on an electronic assembly saving space and easing assembly.
