Active element array substrate and method for manufacturing same

Abstract

An active element array substrate comprises a soft substrate, a grid, a dielectric layer, a channel layer, a source electrode, a leakage electrode and a pixel electrode. The soft substrate defines a transistor zone and a transmitting zone, the transistor zone and the transmitting zone are adjacent, and the gird is located on the soft substrate in the transistor zone; the dielectric layer covers the grid and the soft substrate, a part of dielectric layer located at the upper part of the grid possesses a first thickness, a part of dielectric layer located on the soft substrate in the transmitting zone possesses a second thickness, and the second thickness is less than the first thickness; the channel layer, the source electrode and the leakage electrode are located on the dielectric layer in the transistor zone, the channel layer is located at the upper part of the grid, and the source electrode and the leakage electrode are located at the two sides of the channel layer and are electrically connected with the channel layer separately; the pixel electrode is located on the dielectric layer in the transmitting zone and is electrically connected with the leakage electrode.

Description

technical field [0001] The invention relates to an active element array substrate and a manufacturing method thereof. Background technique [0002] The Electro-Phoretic Display (EPD) was originally developed in the 1970s, and its characteristic is to include charged balls. The ball is white on one side and black on the other. When the electric field is changed, the ball will turn up and down and take on different colors. The second generation of electrophoretic displays was developed in the 1990s. It is characterized by microcapsules instead of traditional balls, and the capsules are filled with colored oil and charged white particles. Through the control of the external electric field, the white particles move up or down. When the white particles go up (close to the direction of the reader), they show white, and when they go down (away from the direction of the reader), they show white. The color of the oil. [0003] In general, most electrophoretic displays use glass a...

Problems solved by technology

However, since the thermal expansion coefficient of the plastic is very different from that of the glass carrier, and even from the thermal expansion coefficient of the inorganic dielectric layer (eg gate dielectric layer, protective layer) on the active element array substrate, it is difficult to It is easy to cause stress accumulation in the active device array substrate and the glass carrier, so that the active device array substrate and the glass carrier are deformed, resulting in collisions or poor adsorption of the machine.
