Display substrate, preparation method thereof and display device

Abstract

The embodiment of the invention provides a display substrate, a preparation method thereof and a display device. The display substrate comprises a plurality of display units which are regularly arranged, each display unit comprises a light-emitting area and a transparent area, and each light-emitting area comprises a first signal line and a second signal line which are vertically crossed to definea plurality of sub-pixels; the first signal line comprises a first switch scanning line and a first compensation scanning line which define a first sub-pixel row, and a second switch scanning line and a second compensation scanning line which define a second sub-pixel row, and the first switch scanning line and the second switch scanning line are arranged between the two sub-pixel rows; the second signal line comprises a first data line and a first power line which define a first sub-pixel column, and a second data line and a second power line which define a second sub-pixel column, and the first data line and the second data line are arranged between the two sub-pixel columns. According to the embodiment of the invention, the problems of relatively low resolution, relatively low transparency and the like of an existing transparent display device are solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display substrate, a preparation method thereof, and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) has the advantages of active light emission, ultra-thin, large viewing angle, high brightness, high contrast, continuously adjustable light color, low cost, fast response, low power consumption, light and thin, and can be With the advantages of special-shaped and flexible display, it has gradually become a promising next-generation display technology. Among them, the Active Matrix (AM) OLED is a current-driven device, which uses an independent transistor (Thin Film Transistor, TFT) to control each sub-pixel, and each sub-pixel can be continuously and independently driven to emit light. [0003] With the continuous development of display technology, OLED technology is more and more used in transparent display. Transparent display is an impor...
