Pixel structure and OLED display panel with same

Abstract

The invention provides a pixel structure and an OLED display panel with the same. The involved pixel structure comprises a pixel defining layer with an opening, a first electrode and a color error adjusting layer arranged in the opening, wherein the first electrode is arranged below the pixel defining layer and at least part of the surface of the first electrode passes through the opening to be exposed; the color error adjusting layer has a side edge part attached to the inner wall of the opening of the pixel defining layer and an organic light emitting layer covering the color error adjustinglayer; and the inner surface of the side edge part is configured to be inclined outwardly from bottom to top and is electrically connected with the first electrode. Based on the specific design of the pixel structure, the part of the organic light emitting layer located on the side edge part of the color error adjusting layer forms compensation for brightness attenuation of light under a large viewing angle, the light brightness attenuation degree under the large viewing angle is further reduced, and the color error problems involved in the prior art can be weakened or completely avoided.

Description

technical field [0001] The embodiments of the present invention relate to the field of organic light-emitting display technologies, and in particular to a pixel structure and an OLED display panel having the pixel structure. Background technique [0002] Organic light-emitting diode (OLED) display devices have self-illumination, low driving voltage, high luminous efficiency, short response time, high definition and contrast, large viewing angle, wide operating temperature range, and can realize flexible display and large-area full-color display, etc. With many advantages, it is recognized by the industry as the display device with the most development potential. [0003] According to the driving method, OLED display devices can be divided into two categories: passive matrix OLED (Passive Matrix OLED, PMOLED) and active matrix OLED (Active Matrix OLED, AMOLED). Among them, AMOLED has pixels arranged in an array, belongs to the active display type, has high luminous efficienc...

Problems solved by technology

[0005] For the current OLED display panel, each luminous pixel usually includes sub-pixels with three different luminous colors: R (red), G (green), and B (basket). The increase of the viewing angle has different degrees of attenuation, which leads to the phenomenon of color shift (ColorShift) in the large viewing angle of the display screen with normal light emission under the front viewing angle.
