Abstract: A driving method of a display panel is provided, including setting the first red, first green, first blue, second red, second green, and second blue multiplexed signals. In the 2i−1th multiplexing period, the charging time of the sub-pixels corresponding to the switching units controlled by the first red, the first green, and the first blue multiplexed signals is earlier than that controlled by the second red, the second green, and the second blue multiplexed signals. While In the 2ith multiplexing period, the charging time of the sub-pixels corresponding to the switching units controlled by the first red, the first green, and the first blue multiplexed signals is later than that controlled by the second red, the second green, and the second blue multiplexed signals. The method will eliminate the stripe feeling of the scream picture displayed on the display panel and so improve the display quality.

Abstract: A light valve device includes a driving substrate having a shading zone and a photic zone. A shading unit includes a first shading plate, two driving devices, and second shading plates respectively connected to the two driving devices. The driving devices and the first shading plate are fixed in the shading zone adjacent to the driving substrate. The first shading plate is between the two driving devices. The driving devices are operable to drive the two second shading plates close to the first shading plate to make the second shading plates face the photic zone of the driving substrate for preventing light entering the driving substrate. By locating the light valve device under the sub pixel, the dynamic contrast can be raised to promote the display effect.

Abstract: A touch device and a touch method of a flexible OLED display apparatus are provided. The touch method includes: acquiring a variation value of a cathode voltage when the display mode is switched; comparing the variation value of the cathode voltage with a preset threshold value, and when the variation value of the cathode voltage exceeds the preset threshold value, increasing the emitter electrode voltage of the touch electrode layer in the Flexible OLED display apparatus. When the cathode voltage changes due to the display mode switching, if the variation value thereof exceeds the preset threshold value, the voltage output amplitude of the emitter electrode is increased, so as to keep the amount of variation of the electric quantity of the receiver electrode constant, thereby keeping the electric quantity of the node capacitance between the emitter and receiver electrodes constant and enhancing the consistency of touch performance.

Abstract: Provided is a display panel, comprising a substrate, and a display area and a non-display area formed on the substrate; wherein metal traces are disposed on one side of the non-display area to electrically connect an integrated circuit in the non-display area with an external structure integrated with a driver integrated circuit (IC) for driving the integrated circuit in the non-display area by the external structure integrated with the driver IC to illuminate the display area. By bonding the driver IC to the external structure, the area ratio of the bonding area of the driver IC on the display panel is reduced to increase the screen occupation ratio of the display panel.

Abstract: A manufacturing method of a TFT substrate uses a top gate structure and the entire process can be completely done with seven masks. The number of masks used is reduced. The manufacturing process of a TFT substrate is simplified. Product yield can be increased to effectively improve productivity. Heavy and light ion doping can be simultaneously achieved with one single doping operation so that manufacturing cost can be reduced. By subjecting two ends of a semiconductor pattern to heavy ion doping to form a source electrode and a drain electrode, the manufacturing steps can be reduced and the source electrode and the drain electrode so formed do not need to extend through a via hole formed in an interlayer dielectric layer to contact the two ends of the active layer thereby effectively reducing contact resistance and improving product yield. Also provided is a TFT substrate manufactured with the method.
