Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display, and more specifically to a special-shaped display screen which can avoid the appearance of color dots. Background Art

[0002] There are usually multiple red, green and blue pixels on the color film substrate. Normally, the area of ​​each red, green and blue pixel is the same, so the brightness of the light emitted by each red, green and blue pixel is also the same. However, if a special-shaped display screen with an arc edge is used, the red, green and blue pixels at the edge will be cut by the special-shaped structure. The shape of the red, green and blue pixels after cutting is jagged. Generally, this special-shaped structure is covered by the outer BM edge to form an arc shape. Although the arc is very smooth, the edge pixels are not fully displayed, which is prone to "color point" problems. Utility Model Content

[0028] Due to S R / D R =S G / D G =S B / D BThat is, the larger the remaining area of ​​the cut pixel, the thicker the color filter film above it, making it lower the brightness that can be transmitted; the smaller the remaining area of ​​the cut pixel, the thinner the color filter film above it, making it higher the brightness that can be transmitted.
