Problems solved by technology

However, since the luminance of different color light-emitting areas has different degrees of attenuation with the increase of the viewing angle, it will cause color shift when observed under a large viewing angle.
Therefore, for the display panel, the problem of large viewing angle deviation needs to be solved urgently

Embodiment Construction

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0031] In the existing display panels, the luminance of different color light-emitting regions has different degrees of attenuation as the viewing angle increases. The attenuation rate of blue light is small, so that the brightness of blue light is the highest, and the brightness of red light and green light are relatively low. What you see is blue, that is, the white picture is bluer at a large viewing angle.

[0032] Such as figure 1 As shown, the embodiment of the present application provides a display panel, including a light-emitting display layer 100 and a photoresist layer 200, and the light-emitting display layer 100 includes a first light-emitting unit 121, a second light-emitting unit 122, and a third light-emitting unit 123, and the third light-emitting unit The...

Abstract

The invention relates to the technical field of display, in particular to a display panel. The display panel comprises a light-emitting display layer and a light resistance layer, the light-emitting display layer comprises a first light-emitting unit, a second light-emitting unit and a third light-emitting unit, and the brightness attenuation rate of light emitted by the side view angle of the third light-emitting unit is smaller than that of light emitted by the side view angles of the first light-emitting unit and the second light-emitting unit. The light resistance layer is located at the side, facing the light-emitting face, of the light-emitting display layer, and comprises a plurality of first sub light resistance layers, second sub light resistance layers and third sub light resistance layers, the first sub light resistance layers are arranged correspondingly to the first light emitting units, the second sub light resistance layers are arranged correspondingly to the second light emitting units, and the third sub light resistance layers are arranged correspondingly to the third light emitting units, wherein the edge thickness of the first sub-photoresist layer and / or the second sub-photoresist layer is smaller than the edge thickness of the third sub-photoresist layer. According to the display panel, the phenomenon of color cast under a large viewing angle can be improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel. Background technique [0002] Organic Light-Emitting Diode (OLED), also known as organic electroluminescent device, refers to a device in which light-emitting materials are driven by an electric field to cause light emission through carrier injection and recombination. Compared with liquid crystal display (LCD) devices, organic light-emitting display devices are lighter and thinner, and have better viewing angles and contrast ratios, and thus have received widespread attention. [0003] Ideally, the luminance of different color light-emitting areas has the same degree of attenuation as the viewing angle increases, so as not to cause color shift. However, since the luminous brightness of different color light-emitting areas has different degrees of attenuation with the increase of the viewing angle, the phenomenon of color shift will occur when viewed ...
