Problems solved by technology

However, this method first requires the use of organic white light emitting diodes that emit light from the top. The process of light emitting diodes with this structure is difficult, and the luminous efficiency is obviously lower than 3-5 times that of conventional structures; The pixel pattern of the color film needs to be precisely aligned with the luminescent pixel pattern of the driving substrate, especially for high-density display screens, which requires higher alignment accuracy, which undoubtedly increases the production cost

Embodiment

[0037] The present invention is described in detail as follows with reference to accompanying drawing:

[0038] As shown in the figure, the present invention uses a polysilicon thin film transistor matrix on a transparent glass substrate (1737 glass produced by Corning Corporation of the United States) 1 as an active addressing substrate. The thin film transistor includes an active layer 2A close to a transparent glass substrate, on and around the active layer 2A is a silicon oxide insulating layer 2O, on the silicon oxide insulating layer 2O is a gate 2G, and on the gate 2G is another layer The silicon oxide insulating layer 11, the source 2S and the drain 2D are connected to the active layer 2A through the silicon oxide insulating layers 11 and 2O. On the active substrate is a silicon oxide insulating layer 5, and in the silicon oxide insulating layer 5 there is a contact hole 3 connected to the drain electrode 2D of the driving tube. On the silicon oxide insulating layer 5 ...

Abstract

The color display comprises the polysilicon thin film transistor, the high temperature color film, the low temperature transparent conductive thin film deposited on the color film and the organic white light thin film diode. Preparing the color display does not need to reach the exact positioning among the evaporation mask, the upper cover board and the lower base plate so that using the high effective common structure of organic white light diode can obtain the color display screen with high density. Thus, the manufacturing cost is lowered; the rate of production and the quality are raised. The invented color display screen is the optimal screen for handset and palm computer and other displays.

Description

Technical field [0001] The invention relates to a display technology, in particular to an organic white light diode color display with an active address-selection front color film and a preparation method thereof. Background technique [0002] The active site-selected color organic white light diode display technologies that have been reported are mainly divided into two categories: one is to use a mask method to evaporate red, green, and blue organic light-emitting thin film diodes on transparent pixels to achieve color display. , "Active Matrix LowTemperature Poly-Si TFT / OLED Full Color Displays: Development Status" (SID 00 Digest, p974-977,) as reported by G. Rajeswaran and M. Itoh et al. The second is to use organic light-emitting diodes that emit light on the top (blue light or white light), and cooperate with the color-changing film or color film or other types of optical thin-film devices on the upper cover to realize color display, such as the Chinese patent CN 12286...
