Embodiment 1

[0050] This embodiment is a preparation embodiment of an active matrix display device A, such as figure 2 As shown, the active matrix display device is composed of the following four parts: a backlight module 1 , a TFT module 2 , an electrochromic module 3 , and a traditional filter 4 .

[0051] Wherein, the backlight source is a white light OLED lighting device, and can also be any planar white light source, such as LED, LEC, CCFL, etc., all of which can achieve the purpose of the present invention and belong to the protection scope of the present invention. If a point light source or a line light source is used, in order to make the backlight module 1 emit light uniformly, a light guide plate should also be provided in the backlight module 1 . The white light OLED lighting device consists of a glass or flexible substrate 101, an OLED anode 102, and a functional layer 103 (the functional layer 103 includes one or more of a hole injection layer, a hole transport layer, a ligh...

Embodiment 2

[0058] This embodiment is a preparation embodiment of an active matrix display device B, such as image 3 As shown, the active matrix display device is composed of the following three parts: a backlight module 1 , a TFT module 2 , and an electrochromic module 3 .

[0059] Among them, the selection and preparation methods of the backlight module 1 and the TFT module 2 are the same as in the embodiment 1, the only difference is that a layer of extremely low transmittance is prepared on the back plate of the first TFT 201 except for the anode 203 of the electrochromic device. The planarized resin is used as the black matrix 402, covering other areas except the anode 203 of the electrochromic device, to define the electrochromic pixel unit, and also to block light leakage in the outer area of ​​the device.

[0060] The electrochromic device is mainly composed of an anode 203 of the electrochromic device, a cathode 304 of the electrochromic device, an anodic color-developing polyme...

Embodiment 3

[0065] This embodiment is a preparation example of an active matrix display device C, which is composed of the following two parts: a backlight module 1 and an electrochromic module 3 .

[0066] The backlight module 1 includes a white LED planar lighting device and a light guide plate. The specific embodiment is the same as that of the known technology. The electrochromic module 3 is arranged on the LED planar lighting device. The specific embodiment is the same as that of the electrochromic module 3 in Example 2. Preparation.

Abstract

An active matrix display device comprises a backlight module and a pixel unit layer which is arranged on the backlight module, wherein the pixel unit layer comprises a TFT (Thin Film Transistor) module and an electrochromic module; each pixel unit comprises a TFT (Thin Film Transistor) and an electrochromic device; the electrochromic device comprises an anode, a cathode as well as an electrochromic material layer and a solid electrolyte layer, wherein the electrochromic material layer and the solid electrolyte layer are arranged between the anode and the cathode; a drain of the TFT is connected with the anode of the electrochromic device through a connecting hole; and the TFT is used for controlling the electrochromic device to change color and / or transmission rate through voltage; simple structure and simple making process are achieved; the electrochromic material is an organic electrochromic material with high response speed as well as vibrant and rich colors; moreover, a light source selecting range of the backlight module is large and flexible display of the device can be achieved.

Description

technical field [0001] The invention relates to the field of electronics, in particular to an active matrix display device with an electrochromic device. Background technique [0002] The full-color display scheme in the prior art can be divided into active light emission and passive light emission. The representative of passive light emission is the liquid crystal display with mature technology now, and the active light emission is the active driving organic light emitting device (English full name is Active Matrix organic lighting emitting display , referred to as AMOLED) and field emission displays. [0003] In the OLED full-color method, RGB (three primary colors are Red, Green, Blue, referred to as RGB) pixel juxtaposition method and color filter (English full name is color filter, referred to as CF) method are the two most mature methods at present. . The RGB pixel juxtaposition method requires a high-precision metal mask to achieve high resolution, which is costly a...
