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.
