Abstract: The present invention provides a timing controller and a controlling method thereof, and a display device with the timing controller. The timing controller includes a storage control module and a frame buffer module connected to each other, and a self-refresh interface connected to the front-end system chip. When the front-end system chip displays a static screen image, the timing controller provided by the present invention can only maintain internal essential modules working and suspend other modules on standby, which reduces power consumption of the timing controller and enhances an operation life of the display device with the timing controller.

Abstract: A three-dimensional dye, a manufacturing method of the three-dimensional dye, and a photoresist mixture are disclosed. A non-planar three-dimensional dye molecular structure is constructed by adding a three-dimensional structure group into a dye molecule, thereby breaking the strong attraction force between the planar conjugation of the dye molecule. Aggregation of dye molecules are prevented, influence of dye molecules on optical paths is eliminated, and thus optical properties and color rendering properties of color filters made by a photoresist liquid are improved.

Abstract: The present invention provides an array substrate and a manufacturing method thereof. The manufacturing method of the array substrate adopts a multi-stage mask to expose and develop, so that a thickness of a remaining photoresist layer in a channel region corresponding to a display region is same as a thickness of a remaining photoresist layer in a channel region corresponding to a GOA region. Therefore, the two channel regions can be completely etched to prevent short-circuiting, and make up for defects of different action efficiency of developers caused by different densities of thin film transistors in the display region and the GOA region.
