Abstract: A driving circuit for a display panel is disclosed. The driving circuit includes at least a driving signal line connected to a display driving signal transmission unit delivering display driving signal produced by the display driving signal transmission unit to sub-pixels of the display panel through the driving signal line; and a number of data signal lines connected to a display data provision unit delivering display data signal produced by the display data provision unit to the sub-pixels. For each subset of the sub-pixels that are of a same component color, at least two data signal lines, starting from different points of time, deliver display data signal to the subset of sub-pixels that are of the same component color. The driving circuit effectively resolves glitches to input signal resulted from heavy transient load to the input signal.

Abstract: The invention provides an OLED display device, comprising: a lower package layer, at least two adjacent OLED display units disposed on the lower package layer, and an upper package layer disposed on the at least two adjacent OLED display units; each OLED display unit comprising a substrate disposed on the lower package layer and a light-emitting layer disposed on the substrate. The at least two adjacent OLED display units are integrally package by the lower and the upper package layers. Therefore, a packaging structure for each OLED display unit is not necessary, so that the light-emitting layer in the adjacent OLED display unit of the present invention achieves seamless docking, which reduces the segmentation sense of the OLED display device, and reduces the gap between adjacent OLED display units and the light-emitting layers as well as improves the display quality of the OLED display device.

Abstract: The present invention provides a mask structure and a COA type array substrate. The mask structure comprises a central light shielding portion (1), a peripheral light shielding portion (3) surrounding the central light shielding portion (1) and conforming to an outer contour shape of the central light shielding portion (1) and a circumambient hollow slit (5) sandwiched between the peripheral light shielding portion (3) and the central light shielding portion (1). The exposure light will diffract through the hollow slit (5) to result in the propagation of the reverse bending and the energy intensity gradient. In conjunction with the negative photoresist, the taper of the finally manufactured color filter layer through hole can be made to be gentle to improve the electrical connection quality between the pixel electrodes and the metal material signal lines for avoiding the display failure.

Abstract: The invention provides a TFT array substrate and LCD panel. The TFT array substrate adopts a Notch design, with a base substrate disposed with a groove at one end. The base substrate comprises a functional area and a peripheral area located outside the functional area, and the planarization layer on the base substrate has a first portion corresponding to the functional area, wherein the first portion adjacent to the groove is provided with at least one pit, and the depth of the pit is smaller than the thickness of the first portion. When the TFT array substrate and the CF substrate are assembled, after the LC is injected between TFT array substrate and CF substrate, the LC accumulation generated in the first portion of the planarization layer near the groove during diffusion is in the pit, thereby making the LC layer thickness uniform and improved quality of LCD panel.

Abstract: A GOA circuit and an embedded touch display panel are provided. By providing an abnormity protection module in the nth-level GOA unit, the level of the scanning signal of the nth-level GOA unit is pulled up when the embedded touch display panel is powered off abnormally. The risk of abnormal display resulted from the residual of charges in pixels due to the abnormal power-off of the GOA circuit is reduced.

Abstract: A signal switching device and a test system are disclosed. A printed wire which is connected with a test circuit can be selected flexibly according to actual situation, and a sufficient distance between adjacent tested printed wires/test printed wires which are used for transmitting a differential signal can be maintained, such that signal interference between the printed wires would not be easily generated. Signals can be effectively separated from each other, and thus the technical problem that signal interference would easily be generated between adjacent tested printed wires/test printed wires which are used for transmitting a differential signal can be solved.
