In the second example of the first embodiment, the grayscale correction circuit 13 includes a first lookup table 131 and a first adder 133. The first lookup table 131 includes the first original grayscale value and the first correction value corresponding to the first original grayscale value, the first lookup table 131 searches the first original grayscale value to obtain the first correction value, and the first adder 133 takes the first original grayscale value The scale value is added to the first correction value to obtain the first correction gray scale value.

In the second embodiment, the gray scale correction circuit 13 adds the first original gray scale value and the first corrected value to obtain the first corrected gray scale value, and the driving circuit 14 is used to obtain the first corrected gray scale value The value is converted into a corresponding driving signal and the driving signal is applied to the pixel 116 of the edge display area 112; the grayscale correction circuit 13 also adds the second original grayscale value and the second correction value to obtain the second corrected grayscale scale value, the driving circuit 14 also applies the drive signal corresponding to the second corrected gray scale value to the pixel 116 of the main display area 110, when the first original gray scale value is equal to the second original gray scale value, the The first corrected gray scale value is greater than the second corrected gray scale value.

Specifically, please refer to FIG. 8. In the first example of the second embodiment, the grayscale correction circuit 13 includes a first lookup table 131 and a second lookup table 132. The first lookup table 131 includes a first The original grayscale value and the first corrected grayscale value corresponding to the first original grayscale value, the second lookup table 132 includes the second original grayscale value and the second corrected grayscale value corresponding to the second original grayscale value The first lookup table 131 obtains the first corrected grayscale value according to the first original grayscale value, and the second lookup table 132 obtains the second corrected grayscale value according to the second original grayscale value.

Specifically, when the display device 10 is in operation, the light emitted from the main display area 110 is basically unchanged after passing through the transmissive portion 122, while the light emitted from the edge display area 112 changes its path after passing through the compensating portion 120. Converging, the image displayed by the pixels 116 of the edge display area 112 is extended to the outside of the edge display area 112 (ie, the non-display area 114 ). At the same time, the compensation part 120 also enlarges the image displayed by the pixels 116 of the edge display area 112, and then the pixels 116 of the edge display area 112 can appear substantially the same as the pixels 116 of the main display area 110 after being enlarged by the compensation part 120. the size of.
