Problems solved by technology

However, if "Ag-free" ITO is selected as the transparent anode, the light L1 emitted by the light-emitting layer 122 will pass through the transparent anode, resulting in light loss.
Although this implementation method can improve the light transmittance of the display panel, it will lead to a decrease in the reflectivity of the anode, weaken the microcavity effect, greatly reduce the light extraction efficiency of the device, and at the same time reduce the color purity of the R / G / B sub-pixels

Abstract

The invention discloses a display panel and an electronic device. Part of the anode of the entire screen of the display panel adopts a structure design of a transparent anode with high light transmittance, and two sub-pixels of the same color are electrically connected through a switching thin film transistor, and share a pixel driving circuit. , can improve the light transmittance of the entire display area without reducing the light extraction performance of the display device, and at the same time, improve the flexibility of the design of the whole machine.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and an electronic device. Background technique [0002] An AMOLED (Active-Matrix Organic Light Emitting Diode, active-matrix organic light-emitting diode) display device is a display device that uses current to drive an OLED (Organic Light Emitting Diode, organic light-emitting diode) to emit light to form a picture. AMOLED display devices have gradually become a new generation of display technology due to their high contrast, wide color gamut, low power consumption, and foldability. Compared with LCD (Liquid Crystal Display, liquid crystal display device), AMOLED has a major advantage of self-illumination. Since it does not require a backlight in LCD, it makes possible the technology of camera under panel (CUP). The under-screen camera technology means that the camera area of ​​the display panel (Panel) can not only display the picture, but also allow t...
