  • Patent number: 9971182
    Abstract: A touch panel and a preparation method therefor, which relate to the technical field of electronic device preparation. The method for preparing a touch panel comprises: firstly, preparing a BM frame layer (1), and then sequentially preparing an ITO1 layer (2), an OC1 layer (3) and an ITO2 layer (4a, 4b) in the BM frame layer (1); then, preparing a window frame layer (5) outside the BM frame layer (1) by means of a printing process; and finally, preparing a designated metal wiring layer (6a, 6b) and an OC2 layer (7). The touch panel and the preparation method therefor solve the problem that a white window frame in the current industry is yellowed easily. Compared with a yellow light lithography for preparing the window frame, the printing process for preparing the window frame is simpler in production process, higher in defect-free rate and lower in corresponding cost, and can reduce pollution from discharge of wastewater and waste gas generated by the chemical solution to the environment.

  • Patent number: 9974142
    Abstract: An electronic display assembly which allocates power to a plurality of displays without exceeding a maximum current level for the circuit is disclosed. An exemplary system preferably includes an AC current sensor, a power load sharing controller, ambient light sensors for each display, and a brightness controller for each display. A maximum total current draw may be selected. The ambient light contacting each display may be measured and a corresponding desired brightness calculated. Depending on the present amount of current draw, the system determines if the displays can be driven at the desired brightness without exceeding the maximum total current draw. If yes, the displays are driven at their desired brightness. If no, the desired brightness for each display may be slightly reduced to prevent exceeding the maximum total current draw. Thus, as the ambient light varies between the displays, the available power may be shared.

  • Patent number: 9921696
    Abstract: Electrode configurations for reducing wobble error for a stylus translating on a surface over and between electrodes of a touch sensor panel is disclosed. In some examples, electrodes associated with a more linear signal profile are correlated with lower wobble error. In some examples, electrodes are coupled to adjacent electrodes via diffusing resistors such that the signal profile for each electrode is spread to be more linear. In some configurations, the value of the diffusing resistors and series resistance associated with an electrode is selected based on a desired signal profile for that electrode. In some examples, the series resistance can include a trace resistance and a compensating resistance. The compensating resistance can compensate for a variance in trace resistance between electrodes, thus making series resistance substantially equal for each of the electrodes.

  • Patent number: 9916793
    Abstract: To reduce the effect of external light and to improve the accuracy of detecting the location of a touch. In an image-capture period, light emission from a self-light-emitting element is controlled, and imaging data at the time of displaying white on a display screen and imaging data at the time of displaying black on the display screen are output from each sensor pixel. The location of a sensor pixel where a difference between the two pieces of imaging data output from the same sensor pixel is the greatest is detected. Thus, the location of a touch of the object on the display screen is detected with high accuracy. By utilizing a difference between imaging data at the time of reverse display, the effect of external light can be reduced.
