Embodiment Construction

[0021] refer to figure 1 , figure 1 It is a schematic structural diagram of the first embodiment of the double-sided display panel of the present invention. In this embodiment, the double-sided display panel 100 includes a plurality of pixel units arranged in an array, and each pixel unit includes front display pixels 11 and back display pixels 12. The display pixels 11 realize the front display of the double-sided display panel 100 , and the rear display pixels 12 realize the reverse display of the double-sided display panel 100 .

[0022] Specifically, the front display pixel 11 includes a first thin film transistor 111 , a first cathode 112 , a first anode 113 and a first light-emitting layer 114 , wherein the first light-emitting layer 114 is disposed between the first cathode 112 and the first anode 113 between. The first anode 113 is electrically connected to the drain 1111 of the first thin film transistor 111 . And the drain 1111 of the first thin film transistor 11...

Abstract

The invention discloses a double-sided display panel and a double-sided display device. The double-sided display panel comprises a plurality of pixel units which are arranged in an array, wherein each pixel unit comprises a front display pixel and a reverse display pixel; each front display pixel comprises a first thin-film transistor, a first cathode, a first anode and a first light-emitting layer; each first light-emitting layer is arranged between each first cathode and each first anode; each first anode is electrically connected with a drain of each first thin-film transistor; each reverse display pixel comprises a second thin-film transistor, a second cathode, a second anode, a second light-emitting layer and a reflecting layer; each first light-emitting layer and each reflecting layer are arranged between each second cathode and each second anode; each second anode is electrically connected with the drain of each second thin-film transistor; each reflecting layer is arranged on the side surface, departing from each second light-emitting layer, of each second cathode; the drain of each first thin-film transistor is used for preventing light of each first light-emitting layer from outgoing from the reverse surface of the display panel; each reflecting layer is used for preventing the light of each second light-emitting layer from outgoing from the front surface of the display panel. The double-sided display panel disclosed by the invention is simple to prepare and easy to lighten and thin.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a double-sided display panel and a double-sided display device. Background technique [0002] At present, the display panel is mainly displayed on one side, but in many occasions, such as digital signage, window inquiry facilities, advertising playback facilities in public places such as exhibition halls, there are often two people viewing the display screen from the front and back sides of the display panel at the same time. . [0003] In order to realize double-sided display, if an LCD (Liquid Crystal Display, liquid crystal display) panel is used, no light source can be placed on both sides of the panel, and only ambient light can be used as the light source, and the brightness is very limited. Therefore, at present, two independent LCD panels are generally combined. In order to realize the display, a relatively complicated connection and driving relationship between the two...
