Non-uniform edge processing method for display screen and display using the same

The invention relates to a driving method for a display, and more particularly to a driving method for making a display with rounded corners display a uniform display effect at rounded corners.

Rounded corners have been used on display panels for many years, but they are all made with pixels as the unit of cut and have obvious jagged edges.

In order to solve the above-mentioned problems, it is known that a technical solution for designing a cut angle using a sub-pixel unit is used to generate a visually smooth arc.

However, if the sub-pixels are used as the design unit, the digital image correlation (DIC) method is required for cooperation. Otherwise, defects may occur due to incomplete boundary pixels. For example, when the rounded edges of a picture are (_, g, b) and (_, _, b), if they are not processed by the circuit, noise edges will appear.

In order to solve the foregoing problems, a novel display driving method is urgently needed in the art.
