Embodiment Construction

[0028] Organic light-emitting diodes (Organic light-emitting diodes, OLED) display panels have the advantages of low operating voltage, fast response speed, high luminous efficiency, wide viewing angle and wide operating temperature, which is conducive to thinning, low power consumption and curved surface design of display devices. . Moreover, in an OLED display panel, pixel circuits are usually used to drive the OLED to emit light. Pixel circuits usually reset the gate of the drive transistor before writing data to the OLED, e.g. figure 2 The pixel circuit shown, figure 2 A schematic circuit structure diagram of a pixel circuit provided by an embodiment of the present invention; it includes 5 switching transistors: M1-M5, 1 driving transistor M0 and 1 capacitor C. The corresponding input timing diagram is as follows figure 2 as shown, image 3 for figure 2 The corresponding input timing diagram for the pixel circuit shown. In the T1 phase, the first scan line Scan1 ...

Abstract

The invention discloses an OLED display panel and a display device, comprising a display area, a middle area and a non-display area, wherein the second display area in the display area is divided into two display sub-areas by the middle area. The first scanning line corresponding to the pixels in the display sub-region includes a first sub-line extending along the row direction, a second sub-line extending along the row direction, and a third sub-line; wherein, the first scanning line of the nth first scanning line One sub-line is connected to the nth row of pixels, the second sub-line is connected to the n+1th row of pixels, and one end of the first sub-line close to the middle area is connected to the second sub-line through the third sub-line. That is to say, the first scanning line is composed of the first sub-line, the second sub-line and the third sub-line in series, and it is equivalent to connecting two rows of pixels on the first scanning line, so that the pixels on the scanning line in the display sub-region The loading is close to the loading of the pixels on the scanning line in the first display area, so as to avoid the problem of uneven display.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display panel and a display device. Background technique [0002] With the development of display technology, the full screen has a large screen-to-body ratio and an ultra-narrow bezel. Compared with ordinary display screens, it can greatly improve the visual effect of the viewer, and thus has received widespread attention. At present, in a display device with a full screen such as a mobile phone, in order to realize the functions of Selfie, video call and fingerprint recognition, a front camera, an earpiece, a fingerprint recognition area or physical buttons are usually arranged on the front of the display device. [0003] In order to achieve full-screen display, such as figure 1 In the schematic structural diagram of the display panel shown, a middle area 1 is set in the display area of ​​the display panel, and a front camera 10 , an earpiece 20 , etc. are set in the ...
