Abstract: In a driving system of a display device, wires are arranged on a first connection unit, a second connection unit and a third connection unit and the traces are arranged on a first circuit board, a second circuit board and a third circuit board accordingly. The electrical path is established on the aforesaid circuit boards and the aforesaid connection units. One end of the electrical path is connected to the power supply voltage, and the other end is connected to the input end of a timing controller. When all the connection units are connected, the power supply voltage is inputted to the timing controller via the path, and the timing controller outputs the power supply control signal for controlling the display device to power on. When the connection units are poorly connected, the timing controller outputs a power supply stopping control signal to stop powering the display device.

Abstract: A liquid crystal panel including an array substrate and a color filter substrate which are disposed opposite and multiple fan-out lines and a color resist layer stacked along a direction from the array substrate toward the color filter substrate. The color film substrate is provided with a common electrode layer. A color resist layer and a columnar spacer are mutually abutted to ensure a distance between the array substrate and the color filter. The color resist layer includes a first plane facing the columnar spacer, and the common electrode line or the common electrode layer surrounds the color resist layer and exposes the first plane. When the liquid crystal panel is subjected to a larger external force such that deformation or displacement occurs between the columnar spacer and the color resist layer, the common electrode line and the common electrode layer are not conductive to form a short circuit.

Abstract: The present invention teaches a CF substrate, its manufacturing method, and a WOLED display device. The CF substrate includes a substrate, a pixel definition layer, and multiple filter patterns. The pixel definition layer has multiple openings, each corresponding to a sub-pixel area of the substrate. Each filter pattern is disposed on the substrate inside an opening of the pixel definition layer, and includes a quantum dot layer and a filter layer sequentially formed on the substrate. The CF substrate requires a single lithographic process to form the openings. The quantum dot layers and filter layers of the filter patterns are then formed by solution film formation in the openings, effectively simplifying the manufacturing process and enhancing the production efficiency. Applying the CF substrate to a WOLED display device also enhances the lighting efficiency, color gamut, and product quality of the WOLED display device.

Abstract: A preparation method of a black matrix on a glass substrate and an application of the preparation method are provided. The method includes the following steps: Step S1, providing a glass substrate and forming a photoresist layer on the glass substrate by applying a photoresist; Step S2, forming a plurality of photoresist grooves on the photoresist layer; Step S3, filling the photoresist grooves with a black matrix photoresist; Step S4, exposing the black matrix photoresist to obtain the black matrix. The method may make a line width of the black matrix thinner, make a taper angle larger, and satisfy the requirement of high resolution, which improves aperture ratio of products. Furthermore, because steps of development process decrease in number and become simpler, the method is easy to be realized without difficulties. Therefore, occurrences of a small taper angle, undercut, and peeling phenomenon of the black matrix are reduced.
