Patent ID: 11199923

Abstract:
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.
