Embodiment Construction

[0020] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0021] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected t...

Abstract

The present invention relates to a display panel, including a substrate, the substrate includes a display area and a non-display area, the non-display area is arranged around the display area, and the display area includes pixel units arranged in an array; The display panel also includes a driving unit, a working power supply and a compensation power supply; the working power supply and the compensation power supply are arranged in the non-display area, and are respectively located at both ends of the display area; the driving unit is connected to the working power supply and the compensation power supply are used to drive the working power supply and the compensation power supply to supply power to the pixel unit. The above-mentioned display panel is provided with a working power supply and a compensation power supply at both ends of the display area, so that the power supply voltage of the pixel units from one end of the display area to the other end is the same, and the phenomenon of uneven display brightness is eliminated.

Description

technical field [0001] The invention relates to the display field, in particular to a display panel, a display device and a preparation method. Background technique [0002] In an organic light emitting display panel, the brightness of the display panel is proportional to the pixel current flowing through the OLED device. Wherein, the power supply voltage is transmitted to each pixel circuit through the signal line after being input outside the effective display area. However, since the signal input line has a certain resistance, the power supply voltage will form a voltage drop on the signal line during the transmission process, resulting in uneven brightness from one end to the other end of the display panel. Contents of the invention [0003] Based on this, it is necessary to provide a display panel and a display device to solve the problem of uneven brightness from one end to the other end of the display panel due to the voltage drop of the signal line. [0004] A di...
