  • Publication number: 20170025480
    Abstract: An in-cell touch panel is disclosed. The in-cell touch panel includes a plurality of pixels. A laminated structure of each pixel includes a substrate, an OLED layer, an encapsulation layer, a light-blocking layer, a first conductive layer and a second conductive layer. The OLED layer is disposed above the substrate. The encapsulation layer is disposed above the OLED layer opposite to the substrate. The first conductive layer is disposed under the light-blocking layer. The second conductive layer is disposed under the encapsulation layer.

  • Publication number: 20160328061
    Abstract: An in-cell touch panel is disclosed. The in-cell touch panel includes a plurality of pixels. Each pixel has a laminated structure bottom-up including a substrate, a TFT layer, a liquid crystal layer, a color filter layer, and a glass layer. The TFT layer is disposed on the substrate. A first conductive layer and a common electrode are disposed in the TFT layer. The first conductive layer is arranged in mesh type. The liquid crystal layer is disposed on the TFT layer. The color filter layer is disposed on the liquid crystal layer. The glass layer is disposed on the color filter layer. The design of touch electrodes and their trace layout in the in-cell touch panel of the application is simple and it can effectively reduce cost and reduce the RC loading of the common electrode.

  • Publication number: 20160314333
    Abstract: A capacitive fingerprint sensing apparatus includes a scanning driver, a sensing driver, sensing lines, scanning lines, and sensing electrodes arranged in a regular way. In a self-capacitive sensing mode, scanning driver scans sensing electrodes through scanning lines and sensing driver performs self-capacitive sensing on sensing electrodes through sensing lines to obtain a first fingerprint pattern. In a mutual-capacitive sensing mode, scanning driver scans sensing electrodes through scanning lines and sensing driver performs mutual-capacitive sensing on at least one pair adjacent sensing electrodes through sensing lines to obtain a second fingerprint pattern. The first fingerprint pattern and second fingerprint pattern are synthesized to a synthesized fingerprint pattern having resolution larger than first fingerprint pattern and second fingerprint pattern along at least one direction.
