Problems solved by technology

[0006] The defect of the existing AMOLED display panel is that the red light-emitting device 1, the green light-emitting device 2 and the blue light-emitting device 3 have different decay speeds, and the blue light-emitting device 3 has the fastest decay and the lowest life span, which seriously affects the performance of the display panel. The service life of the display panel will show serious color shift with the increase of use time
If the aperture ratios of the red light-emitting device 1, green light-emitting device 2 and blue light-emitting device 3 are adjusted, the total aperture ratio of the pixel will decrease again.

Embodiment Construction

[0030] In order to improve the service life of the display panel without reducing the total aperture ratio of the pixel, an embodiment of the present invention provides an organic light emitting diode (hereinafter referred to as OLED) display pixel, a display panel and a display device. In the technical solution of the present invention, the red light-emitting device, the green light-emitting device and the blue light-emitting device are arranged obliquely relative to the side of the pixel, and the blue light-emitting device is located between the red light-emitting device and the green light-emitting device and has the longest length. Under certain conditions, the opening area of ​​the blue light-emitting device of this pixel structure is larger than that of the red light-emitting device and the green light-emitting device, and the current density of the blue light-emitting device is smaller. Therefore, compared with the prior art, the total pixel opening can be reduced. Under...

Abstract

The invention relates to the field of display technology, and discloses an organic light emitting diode display pixel, a display panel and a display device, which can improve the service life of the display panel without reducing the total aperture ratio of the pixel. An organic light emitting diode display pixel, including a red light emitting device, a green light emitting device and a blue light emitting device arranged in parallel and inclined relative to the side of the pixel, wherein: the red light emitting device and the green light emitting device are located at two sides of the blue light emitting device On the other hand, the lengths of the blue light-emitting devices are respectively greater than the lengths of the red light-emitting devices and the green light-emitting devices.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic light emitting diode display pixel, a display panel and a display device. Background technique [0002] OLED (Organic Light-Emitting Diode, organic light-emitting diode, referred to as OLED) display is thin, light, wide viewing angle, active light emission, continuously adjustable light color, low cost, fast response, low energy consumption, low driving voltage, With the advantages of wide operating temperature range, simple production process, high luminous efficiency and flexible display, it has been listed as a promising next-generation display technology. [0003] The basic structure of an OLED includes an anode, a cathode, and an organic light-emitting layer between the anode and the cathode; OLED luminescence refers to the phenomenon that the organic light-emitting layer is driven by an external electric field, and the phenomenon of luminescence is caused by car...
