[0021] In order to make the above-mentioned purposes, features and advantages of the application more obvious and easy to understand, the specific embodiments of the application will be described in detail below with reference to the drawings.

[0022] The effective surface of the screen four corners and the camera position of the full-screen LCD mobile phone is arc-shaped design, and the effective surface edge of the corresponding color filter layer is also arc-shaped design. Before forming the color filter layer, openings need to be formed in the matrix layer. However, the current design method only processes the openings in the outermost row of the color filter close to the edge. For details, please refer to Figure 1 From Figure 1 It can be seen from the figure that the area of the openings 105 in the initial step unit 101 in the step unit is quite different from the area of the openings 105 in the peripheral secondary initial step unit 102, the area of the openings 105 in the first intermediate step unit 103, the area of the openings 105 in the second intermediate step unit 104, and the area of the openings 105 in the third intermediate step unit 106. When transitioning from the edge area far away from the conventional area to the edge area close to the conventional area, the sawtooth shape is easy to appear, which leads to poor visual effect and limits the use of the filter to some extent.

[0023] In order to solve the problem of the jagged transition from the edge area to the non-edge area, resulting in poor visual effect, the present application provides a pixel adjustment method, by adjusting the area of the opening between the step units and the distance between the openings in the step units, the area of the opening and the size distribution of the opening in the rounded edge area are comprehensively adjusted, so that when changing from the rounded edge area far away from the normal area to the rounded edge area close to the normal area, the transition surface between the rounded edge areas becomes smoother, reducing the visual difference, thereby improving the visual effect of the final formed filter, improving the quality of the filter and expanding the use range of the filter.

A mask with a preset pattern is used, and ultraviolet light is irradiated onto the photoresist coating layer through the mask to complete the exposure process.
