AMOLED pixel structure and display device

Abstract

The invention relates to an AMOLED pixel structure and a display device. The AMOLED pixel structure comprises a plurality of first sub pixels, second sub pixels, and third sub pixels, wherein the third sub pixels are B sub pixels. Central connection lines of two first sub pixel light-emitting regions and two third sub pixel light-emitting regions around a second sub pixel light-emitting region form a virtual isosceles trapezoid. The center of the second sub pixel light-emitting region is located at an intersection point of a perpendicular bisector of the central connection line of the two first sub pixel light-emitting regions around the second sub pixel light-emitting region and a perpendicular bisector of the central connection line of the two third sub pixel light-emitting regions around the second sub pixel light-emitting region. The centers of all first sub pixel light-emitting regions and the centers of all third sub pixel light-emitting regions around the second sub pixel light-emitting region are overlapped with all vertexes of the virtual isosceles trapezoid. Therefore, distances between the first sub pixel light-emitting regions and corresponding via holes are reduced andthe distances between the third sub pixel light-emitting regions and corresponding via holes are increased, so that the distances between the first sub pixel light-emitting regions and the corresponding via holes are equal to the distances between the third sub pixel light-emitting regions and the corresponding via holes and thus the process margin is increased.

Description

technical field [0001] The invention relates to the technical field of AMOLED display, in particular to an AMOLED pixel structure and a display device. Background technique [0002] With the increasing application of high-resolution display devices, the requirements for the resolution of the display devices are also getting higher and higher. In a traditional AMOLED (Active-matrix organic light emitting diode, active-matrix organic light-emitting diode) display device, three sub-pixels are usually used: an R sub-pixel, a G sub-pixel, and a B sub-pixel to form a pixel. At the same time, the anodes of the sub-pixels are respectively electrically connected to the corresponding thin film transistors through the via holes in the planar layer. Wherein, the via holes are usually arranged in an array, and are all located at the same position of the non-light-emitting regions of the corresponding sub-pixels. [0003] However, in a traditional AMOLED display device, due to the large...
