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. It is composed of N×M light-emitting pixel units arranged in a matrix structure, and is characterized in that two groups of driving thin-film transistors (TFT) and two layers of organic light-emitting diodes are stacked on the base layer of each light-emitting pixel unit. The two layers of organic light-emitting diodes are separated by an opaque reflective layer made of insulating material, wherein a group of driving thin film transistors (TFTs) are connected to a layer of organic light-emitting diodes through their source or drain electrodes. The anode of the tube is connected, and another group of driving thin film transistors (TFTs) is connected to the anode of another organic light-emitting diode through its source or drain electrode penetrating through the reflective layer. The beneficial effects of the present invention are: the two layers of light-emitting diodes are separated by an opaque material between the two layers of organic light-emitting diodes in the light-emitting pixel unit, and are respectively driven by two groups of driving thin-film transistors (TFTs), thereby Realize independent light-emitting display on both sides 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...
