Abstract

The invention provides a double-sided display panel and a preparation method thereof. A light-emitting area and a non-light-emitting area surrounding the light-emitting area are defined in a display area of the double-sided display panel; and the double-sided display panel comprises a substrate, a thin film transistor located on the substrate and arranged corresponding to the non-light-emitting area, and a first light-emitting unit and a second light-emitting unit which are located on the substrate and arranged corresponding to the light-emitting area. One of the first light-emitting unit andthe second light-emitting unit is of a top light-emitting structure, and the other one is of a bottom light-emitting structure, wherein one first light-emitting unit and one second light-emitting unitare correspondingly connected to the same thin film transistor, and the first light-emitting unit and the second light-emitting unit display synchronously. Double-sided synchronous display is achieved through one back plate, so that the overall thickness of the double-sided display panel can be reduced, the technological process is simplified, and then the manufacturing cost is saved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a double-sided display panel and a preparation method thereof. Background technique [0002] OLED (organic light emitting diode, organic light emitting diode) display has self-illumination, low driving voltage, high luminous efficiency, short response time, high contrast, wide viewing angle, wide operating temperature range, and can realize flexible display and large-area full-color display, etc. With many advantages, it is recognized by the industry as the display with the most potential for development. [0003] However, at present, there are few reports on OLED double-sided display backplane technology, mainly two array backplanes are laminated back to back and then displayed separately. This design requires two independent OLED panels, resulting in thicker display thickness, poor structure The process is relatively complicated, and the production cost is relativel...
