Problems solved by technology

[0003] like figure 1 As shown, the traditional OLED display includes a substrate 10, a light-emitting device 11, an encapsulation layer 12, and a polarizer 13 (Polarizer) arranged in sequence. The polarizer 13 can effectively reduce the light output rate of the strong ambient light incident on the OLED display to improve the OLED display. Contrast ratio, but cause the OLED to lose nearly 58% of the light output rate
For OLEDs, on the one hand, the use of polarizers makes the light output rate of OLEDs low, which greatly increases the life burden of OLEDs; on the other hand, the thickness of polarizers is large and the material is brittle, which is not conducive to the development of dynamic bending products.

Abstract

The invention provides a display panel and a touch display. A black pixel limiting layer is arranged in the display panel to absorb incident light entering the display panel, so that the display paneland the touch display have good contrast ratio when displaying under strong ambient light, and meanwhile, the light extraction rates of the display panel and the touch display are not reduced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a touch display. Background technique [0002] At present, organic light emitting diode (Organic Light Emitting Diode, OLED) display has attracted much attention as a display device for displaying images. Different from liquid crystal displays (Liquide Crystal Display, LCD), OLED displays not only have high-quality characteristics such as self-luminous characteristics, low power consumption, high brightness, and high response speed, but also have characteristics that are easier to realize foldable. [0003] like figure 1 As shown, the traditional OLED display includes a substrate 10, a light-emitting device 11, an encapsulation layer 12, and a polarizer 13 (Polarizer) arranged in sequence. The polarizer 13 can effectively reduce the light output rate of the strong ambient light incident on the OLED display to improve the OLED display. However, the...
