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

[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] 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-face displayer, consisting of N*M light emitting pixel units which are arranged according to an array structure. The double-face displayer is characterized in that two groups of driving thin film transistors (TFT) and a layer of organic light emitting diode which are stacked on a base layer of each light emitting pixel unit, that a non-transparent reflective layer which is made of an insulation material is positioned on the organic light-emitting diode, a planarization layer is arranged on the reflective layer, the planarization layer is provided with an LCD displayer, an E-paper displayer or an E-Ink displayer, that one group of the driving thin film transistors (TFT) is connected to the anode of the organic light-emitting diode through the source or the drain electrode of the driving thin film transistors (TFT), that the other group of the driving thin film transistors (TFT) passes through the reflective layer and the planarization layer to connect to the driving electrodes of the LCD displayer, the E-paper displayer or the E-Ink displayer through the source or the drain electrode of the driving thin film transistors (TFT). The double-face displayer can combine the flat displayers with various types (LCD, E-paper,E-ink) with the OLED displayer and achieves the double-faced independent illumination display of the combined displayer.

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 the light-emitting pixel units to emit light, OLEDs 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 b...
