Embodiment 1

[0091] In specific implementation, in the above-mentioned organic light-emitting display panel provided by the embodiment of the present invention, when each pixel includes a plurality of sub-pixels, the direction along the edge of the display area points to the inside of the display area, so that each row of pixels can be at the edge of the display area The average value of the capacitance values ​​of the first parasitic capacitances corresponding to the pixels at the location decreases sequentially. In this way, the brightness of the pixels can be gradually reduced in the direction along the edge of the display area to the non-display area, so that the brightness of the organic light-emitting display panel transitions from the edge of the display area to the non-display area, thereby improving the organic light-emitting display. The sawtooth effect and the color fringing effect of the panel can make the viewing effect of the human eye better.

Embodiment 2

[0103] In specific implementation, in the above-mentioned organic light-emitting display panel provided by the embodiment of the present invention, when each pixel includes a plurality of sub-pixels, the direction along the edge of the display area points to the inside of the display area, so that each row of pixels can be at the edge of the display area The average value of the capacitance values ​​of the storage capacitors corresponding to each pixel at the location increases sequentially. In this way, the brightness of the pixels can be gradually reduced in the direction along the edge of the display area to the non-display area, so that the brightness of the organic light-emitting display panel transitions from the edge of the display area to the non-display area, thereby improving the organic light-emitting display. The sawtooth effect and the color fringing effect of the panel can make the viewing effect of the human eye better.

Embodiment 3

[0122] by Figure 2a The pixel circuit shown is an example. Such as Figure 2a The structure of the pixel circuit is shown, and its corresponding timing diagram is as follows Figure 5a shown. Specifically, choose the Figure 5a There are three stages T1, T2 and T3 in the timing diagram shown. Wherein, gate1_n represents the signal input from the first scanning signal line Gate1_n, gate2_n represents the signal input from the second scanning signal line Gate2_n, and emit represents the signal input from the light emission control signal line Emit. In the following, only the working process of the pixel circuit in the sub-pixel at the edge of the display area will be described in detail.

[0123] In the T1 stage, gate1_n=1, gate2_n=0, emit=1, so the second transistor M2 and the fifth transistor M5 are turned on. The turned-on second transistor M2 provides the initialization signal on the initialization signal line Vint to the gate of the driving transistor DTFT and the st...

Abstract

The invention discloses an organic light emitting display panel and a display device. A part, near a non-display area, in a display area for light emitting display is defined as a display area edge, and a pixel on the display area edge is provided with a first capacitor related to a grid of a driving transistor in the pixel; a part, except the display area edge, in the display area is defined as a display area remainder, and a pixel on the display area remainder is provided with a second capacitor related to a grid of a driving transistor in the pixel; a capacitance value of the first capacitor is set to be different from that of the second capacitor, namely, the first capacitor in the pixel on the display area edge and the second capacitor in the pixel on the display area remainder are designed differently; the brightness of the pixel on the display area edge is lower than that of the pixel on the display area remainder, then the color contrast between the display area edge and the non-display area can be reduced, and a sawtooth effect and a color edge effect of the organic light emitting display panel can be relieved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic light emitting display panel and a display device. Background technique [0002] With the rapid development of display technology, in addition to the traditional information display and other functions of display panels, in order to better adapt to the overall structure and use requirements of the environment, the requirements for appearance are also gradually increasing, resulting in special-shaped display panels. The special-shaped display panel is a special-shaped display panel transformed on the basis of the traditional display panel, so that the characteristics of the display panel can better adapt to the overall structure and environment. Special-shaped display panels have been successfully applied to wearable electronic devices such as watches, glasses or smart bracelets, and common special-shaped display panels mainly have fan-shaped, arc-shaped, circular, cyl...
