摘要： Disclosed in the present invention are a method for manufacturing a thin-film transistor, an array substrate, and a display device. The method includes: forming a buffer layer on a substrate; forming a polysilicon layer on the buffer layer; performing a patterning process on the polysilicon layer, to form an active layer; depositing a gate insulating layer on the active layer; depositing a gate metal layer on the gate insulating layer, and performing dry etching on the gate metal layer by using the patterning process and by using a gas containing CO as an etching gas, to form a gate; performing ion implantation on the active layer by using the gate as a mask, to form a source region and a drain region; and depositing a passivation layer on the gate, forming through holes in the gate insulating layer and the passivation layer, and manufacturing a source and a drain.

摘要： The present application relates to a touch display module (10) and a touch display screen. The touch display module (10) comprises a first substrate (100), a second substrate (200), a touch electrode layer (300), a pixel definition layer (400) and a cathode layer (500), a plurality of support portions (600) being provided between the cathode layer (500) and the pixel definition layer (400), and the projection of each support portion (600) on the touch electrode layer (300) being located in a light transmitting hole (310). The light transmitting hole (310) corresponds to a pixel unit (410) and the support portion (600) respectively, so that a distance between a part of the cathode layer (500) on the support portion (600) and the touch electrode layer (300) includes the pixel unit (410), so as to increase the distance between a part of the cathode layer (500) on the support portion (600) and the touch electrode layer (300), thereby reducing coupling capacitance between the touch electrode and the cathode layer (500), and improving the effect of touch sensing.

摘要： A sub-pixel rendering method, comprising the following steps: acquiring a second pixel array corresponding to an original image, each sub-pixel of the second pixel array corresponding to a greyscale value; mapping the second pixel array of the original image onto a first pixel array; respectively finding the central positions of the sub-pixels of the first pixel array and of the second pixel array, determining sub-pixels of the second pixel array positioned in every sub-pixel preset region in the first pixel array and of the same colour as said sub-pixels in the first pixel array, and measuring the distance of same from the central position of said sub-pixels of the first pixel array; on the basis of the distance, calculating the proportional coefficient occupied by the sub-pixels of the second pixel array in the sub-pixels of the first pixel array, and on the basis of the proportional coefficient and the greyscale value of the sub-pixels of the second pixel array, calculating the greyscale value corresponding to each sub-pixel of the first pixel array. The preset sub-pixel rendering method is simple and easy to implement; few hardware resources are required, and software operation is rapid.

摘要： A mask, including a dummy region and at least one effective evaporation region. The at least one effective evaporation region is provided with several first through holes. The dummy region is provided with several second through holes. The second through hole has a same shape as the first through hole, a dimension of the second through hole is equal to a dimension the first through hole, and spacing between the second through holes is equal to spacing between the first through holes. The second through holes are disposed in the dummy region on the outer side of the effective evaporation region. The second through hole has the same shape, dimension, and spacing as the first through hole.

摘要： An organic light emitting diode pixel arrangement structure includes multiple first sub-pixels, multiple second sub-pixels, and multiple third sub-pixels. Two adjacent first sub-pixels are arranged in a first sub-pixel group, two adjacent second sub-pixels are arranged in a second sub-pixel group, two adjacent third sub-pixels are arranged in a third sub-pixel group. The multiple sub-pixels form multiple arrays, and each array includes at least one first sub-pixel, at least one second sub-pixel and at least one third sub-pixel, each of the first, second and third sub-pixel groups corresponds to a square opening of a mask plate in an evaporation process, there is an inclination angle between a side of the square opening and an arrangement direction of a linear evaporation source, and the inclination angle is an acute angle or an obtuse angle.
