Patent number: 9589508Abstract: A pixel driving circuit includes a signal loading component, a storage capacitor, a compensation component, a mirror component, and a drive transistor. In a data transmission stage, the signal loading component transmits a received image data signal to the gate of a drive transistor, which is stored in a storage capacitor; and in a threshold voltage compensation stage, the compensation component connects the gate of the drive transistor to the source of the drive transistor so as to generate a drive signal dependent upon the threshold voltage of the drive transistor from the signal stored in the storage capacitor and to drive an organic light emitting diode to emit light, thus eliminating an influence of the threshold voltage of the drive transistor on the current through the organic light emitting diode and preventing the brightness of the organic light emitting diode from varying over its operating period of time.Type: GrantFiled: July 7, 2016Date of Patent: March 7, 2017Assignee: WUHAN TIANMA MICRO-ELECTRONICS CO., LTD.Inventors: Sijie Yang, Chao Dai, Tong Wu

Patent number: 9570034Abstract: The present disclosure relates to a pixel cell circuit of compensation feedback voltage. The pixel cell circuit is provided with the compensation capacitance (C_co), one end of the compensation capacitance (C_co) electrically connects to the compensation level wirings G(m)_co, and the other end of the compensation capacitance (C_co) electrically connects to the drain of the TFT (T1) and the pixel electrode (P). A level of the compensation signals transmitted by the compensation level wirings G(m)_co is opposite to the level of the scanning signals transmitted by the scanning lines G(m). When the pixel electrode has been fully charged, the compensation capacitance generates a pull-up feedback voltage for compensating the pull-down voltage caused by the parasitic capacitance so as to eliminate the effects toward the pixel electrodes caused by the scanning signals transmitted by the scanning lines. This configuration not only decreases the flickers, but also the image sticking.Type: GrantFiled: August 21, 2015Date of Patent: February 14, 2017Assignee: SHENZHEN CHINA STAR OPTOELECTRONICS TECHNOLOGY CO., LTD.Inventor: Hongyuan Xu

Patent number: 9465502Abstract: A multi-touch capacitive touch sensor panel can be created using a substrate with column and row traces formed on either side of the substrate. To shield the column (sense) traces from the effects of capacitive coupling from a modulated Vcom layer in an adjacent liquid crystal display (LCD) or any source of capacitive coupling, the row traces can be widened to shield the column traces, and the row traces can be placed closer to the LCD. In particular, the rows can be widened so that there is spacing of about 30 microns between adjacent row traces. In this manner, the row traces can serve the dual functions of driving the touch sensor panel, and also the function of shielding the more sensitive column (sense) traces from the effects of capacitive coupling.Type: GrantFiled: June 9, 2015Date of Patent: October 11, 2016Assignee: Apple Inc.Inventors: Steven P.
