Problems solved by technology

[0003] However, the double-sided display panel in the prior art is actually a combination of two independent display panels. Its internal structure and the driving system for driving the two independent display panels to emit light are relatively complicated. problems, and the production cost of double-sided display panels is also relatively high, and the thickness of the product is relatively large, which does not meet the trend of thinner and thinner display panels

Abstract

The invention provides a display panel and a display device. The display panel comprises a substrate, and a first anode, a first light-emitting layer, a common cathode, a second light-emitting layer and a second anode which are sequentially arranged on the substrate in a stacked mode, wherein the first anode and the second anode are electrically connected so as to realize double-sided display. Bysharing the same cathode and electrically connecting the first anode and the second anode, double-sided display is realized, the thickness of the display panel can be effectively reduced, and the manufacturing cost of the display panel is reduced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] At present, most of the display devices on the market are based on single-sided display. In many occasions, such as digital signage, electronic communication equipment, cash register facilities, window inquiry facilities, and advertising playback facilities in public places such as exhibition halls, users often need to Viewing the displayed picture from the front and back of the display device at the same time, the double-sided display has gained more and more applications. [0003] However, the double-sided display panel in the prior art is actually a combination of two independent display panels. Its internal structure and the driving system for driving the two independent display panels to emit light are relatively complicated. problem, and the production cost of the double-sided display panel is a...
