Problems solved by technology

[0007] 1. The opposite electrode 190 is set to be light-transmitting, but in this way, the luminescence of one side is opposite to that of the other side, and one side cannot accurately display information, and at the same time it will reduce the luminous quality of both sides
[0008] 2. Use mechanical connection to package the above two OLEDs together or bond two packaged single OLEDs together, which will significantly increase the thickness of the display

Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] Such as figure 2 As shown, it shows an OLED display composed of N×M (N and M are natural numbers) light-emitting pixel units arranged and combined in a matrix structure. Each light-emitting pixel unit is composed of specific materials according to a stacked structure, forming a driving thin-film transistor (TFT) and an organic light-emitting diode of a light-emitting pixel unit, as well as other components such as capacitors and driving thin films that make up a light-emitting pixel unit. Transistor (TFT) etc. (not shown in the figure). Two layers of organic light-emitting diodes are separated by an opaque reflective layer made of insulating material, and a group of driving thin-film transistors (TFTs) pass their source or drain electrodes and a layer of organic light-emitting diodes. The anode is connected, and another grou...

Abstract

The invention relates to a double-sided OLED display, which consists of N*M luminous pixel units which are arranged and combined according to a matrix structure. The double-sided OLED display is characterized in that two groups of drive thin film transistors (TFTs) and two layers of organic light emitting diodes are overlapped on a base layer of each luminous pixel unit, and the two layers of organic light emitting diodes are isolated through an opaque reflecting layer made of insulating material, wherein one group of drive TFTs are connected with anodes of one layer of organic light emitting diodes through sources or drains thereof, and the other group of the drive TFTs are connected with anodes of the other layer of organic light emitting diodes through sources or drains of the drive TFTs running through the reflecting layer. The double-sided OLED display has the advantages that the opaque material is arranged between the two layers of organic light emitting diodes in the luminous pixel unit to isolate the two layers of light emitting diodes, and the display is driven through the two groups of drive TFTs respectively so as to realize double-sided independent luminous display of the display.

Description

technical field [0001] The invention relates to plane display technology, in particular to plane display technology capable of realizing double-sided light emission. Background technique [0002] An organic light-emitting display (OLED, Organic Light-Emitting Display) is a light-emitting display device that can electrically excite fluorescent organic compounds to emit light. OLED is composed of N×M (N and M are natural numbers) light-emitting pixel units arranged in a matrix structure. According to the driving method used to drive light-emitting pixel units to emit light, OLED can be divided into passive matrix (PM, passive- matrix) type or active matrix (AM, active-matrix) type. [0003] figure 1 A sectional view showing a conventional OLED light-emitting pixel unit. refer to figure 1 The manufacturing method and structure of the panel will be described, and the buffer layer 105 is formed on the substrate 100 . A driving thin film transistor (TFT) is then formed by seq...
