Abstract

The invention relates to the technical field of display, and discloses a display panel and a display device. The display panel comprises a first area formed by a front surface pixel array and a secondarea formed by a back surface pixel array, so that double-sided display can be realized; the pixel of the first area comprises a first light-shielding layer, a first thin-film transistor and a top-emitting OLED unit; the first light-shielding layer is arranged, and material of a first anode and a first cathode can be selected, so that emitting and light leakage of the light from the top-emittingOLED unit on the back surface of the display panel can be prevented; the pixel of the second area comprises a second thin-film transistor, a bottom-emitting OLED unit and a second light-shielding layer; the second light-shielding layer is made of a material with a light shielding effect, such as a black film MMCBX or a black matrix BM, and is made on a metal electrode, and the effect of the composite functional electrode thin film can be achieved, so that the light-emitting effect of the back-side display pixels is guaranteed, and light leakage is prevented. The display panel can be a flexiblefolding panel, so that the light and thin double-sided display effect is easy to realize.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] At present, with the rapid development and popularization of electronic products equipped with display screens such as smart phones, wearable devices, vehicle displays, and AR / VR, people are putting forward more and more demands on display devices. Among them, the double-sided screen, as the "prototype" of future multi-screen interaction, has ushered in the beginning of an innovative era. The existing double-sided screen display technology is actually dual-screen display, that is, two screens are used for double-sided display, which is thick, heavy, and costly, and cannot meet people's needs for double-sided screen display. Contents of the invention [0003] The invention discloses a display panel and a display device, and aims to provide a light and thin double-sided display screen. [0004] To achi...
