Embodiment Construction

[0019] Certain words are used to refer to specific components in the description and claims, and those skilled in the art should understand that manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a basis for distinction. The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] figure 1 It is a structural schematic diagram of the AMOLED panel of the first embodiment of the present invention. Such as figure 1 As shown, the AMOLED panel 10 includes a first region A with different film thicknesses, a second region B, and a plurality of pixels 11 distributed on the AMOLED panel 10 in a matrix, wherein each pixel 11 includes a unit pixel driving circuit 111 and a light emitting element 112 , the unit pixel driving circuit 111 is used to drive ...

Abstract

The invention discloses a method for improving uneven display brightness of an AMOLED panel and the AMOLED panel. The panel at least includes a first region and a second region with different film thicknesses; wherein, the storage capacitors arranged in the unit pixel driving circuits in the first region and the second region have different capacitance values, so that the first region and the second region have different capacitance values. The two regions have the same display brightness. In the present invention, different storage capacitance values ​​are set in areas with different film thicknesses, and the display brightness of pixels corresponding to different storage capacitance values ​​is different, so that the problem of uneven display brightness of the AMOLED panel caused by uneven film thickness can be improved. Thus, the display quality of the AMOLED is improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a method for improving uneven display brightness of an AMOLED panel and the AMOLED panel. Background technique [0002] Organic Light Emitting Diode (OLED) display panel has many advantages such as self-illumination, low driving voltage, high luminous efficiency, short response time, high definition and contrast, nearly 180° viewing angle, and wide operating temperature range. Widely used in smartphones, tablets, full-color TVs, etc. [0003] OLED display panels can be divided into passive matrix (Passive Matrix, PM) type and active matrix (Active Matrix, AM) type according to the driving method. Among them, active matrix organic light-emitting diode (AMOLED) technology is the focus of flexible display. One of the directions of development. [0004] The problem of uneven display brightness of AMOLED panels is one of the common problems of AMOLED panels, among whi...
