Problems solved by technology

[0011] 1. The opposite electrode 190 of the OLED 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
[0012] 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

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] 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. Two groups of driving thin film transistors (TFT) and a layer of organic light-emitting diodes are stacked on the base layer 1 of each light-emitting pixel unit. The reflective layer 10 has a planarization layer 11 above the reflective layer 10, and an LCD, E-paper or E-Ink display is provided above the planarization layer 11, wherein a group of driving thin film transistors (TFT) passes through it The source or drain electrode is connected to the anode of the organic light-emitting diode, and another group of driving thin film transistors (TFT) penetrates the reflective layer 10 and the planarization layer 11 through its source or drain electrode and connect...

Abstract

The invention relates to a double-sided display, which is formed by arraying and combining N*M luminous pixel units according to a matrix structure. The double-sided display is characterized in that: the base layer of each luminous pixel unit is laminated with two groups of driving thin film transistors (TFT) and a layer of organic light emitting diodes; a lightproof reflecting layer made from an insulation material is arranged on the organic light emitting diodes; a planar layer is arranged on the reflecting layer; an LCD, E-paper or E-Ink display is arranged on the planar layer, wherein one group of driving thin film transistors (TFT) is connected with the anode of the light emitting diode through the source or drain electrodes of the driving thin film transistors (TFT) and the other group of driving thin film transistors (TFT) runs through the reflecting layer and the planar layer through the source or drain electrodes of the driving thin film transistors (TFT) to be connected with the driving electrode of the LCD, E-paper or E-Ink display. The double-sided display has the advantage of realizing independent luminous display on two sides of the combined display by combining different types of flat panel displays (such as LCD, E-paper or E-Ink and the like) and an OLED 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...
