Embodiment

[0031] Such as figure 1 with Figure 4 As shown, in this embodiment, the display device of the present invention includes a display panel 100, and the display panel 100 includes a first pixel electrode 110, a second pixel electrode 120, a barrier wall 130, a first light emitting unit 140, and a second light emitting unit 150 , cathode 160 , encapsulation layer 170 and touch layer 180 .

[0032] In this embodiment, the display panel 100 of the present invention is a curved full-screen panel, including a flat display area 101 and a bent display area 102, wherein the bent display area 102 is arranged on both sides of the flat display area 101, The curved display area 102 is bent toward the back of the display panel 100 to realize the 3D curved surface display function of the display panel 100 .

[0033] Such as figure 2 As shown, in this embodiment, the lateral direction of the display panel 100 is defined as a first direction A, and the curved display area 102 is disposed on...

Abstract

The embodiment of the invention discloses a display panel and a display device, the display panel comprises: bending display areas and a plane display area, wherein the bending display areas are arranged on the two sides of the plane display area; first pixel electrodes which are distributed in the flat panel display area in an array mode; and second pixel electrodes which are distributed in the bending display area in an array mode, wherein the size of the first pixel electrode is smaller than that of the second pixel electrode. The display panel and the display device have the advantages that the pixel openings of the bent display area are increased, the current flow of the pixel electrodes of the bent display area is increased, the problem of brightness attenuation in the bent display area is solved, and the brightness of the bent display area and the brightness of the flat display area are balanced.

Description

technical field [0001] The present application relates to the field of panels, in particular to a display panel and a display device. Background technique [0002] With the advancement of science and technology and the continuous improvement of living standards, people have higher and higher requirements for the quality of life. The flagship products of various terminal brands have basically fully used primary bending panels. Especially for small-sized products, such as flexible products such as mobile phones, tablets, and vehicles, there are higher requirements. However, in the current edge surface display, comparing the edge and the middle non-bending area, it can be found that due to 90°Lami (Lami), the brightness of the edge area rapidly decays with the angle, resulting in darker edges of the screen and affecting visual effects; With the concept of "waterfall screen", large curvature bending products, and four-curved surface products, this shortcoming of edge curve flex...
