Display device and temperature compensation method

A display device, comprising:

• a display panel, comprising a pixel array, wherein the pixel array comprises a plurality of pixel structures;
• a first temperature sensor, corresponding to a first area in the pixel array, wherein the first area comprises a portion of the pixel structures, and the first temperature sensor is configured to obtain a first temperature value;
• and
• a temperature compensation circuit, electrically connected to the first temperature sensor, and configured to set a down-sampling position in the first area, and receive a first subpixel value corresponding to the down-sampling position,
• wherein the temperature compensation circuit is configured to obtain a first compensation temperature value at the down-sampling position according to the first temperature value, query a lookup table according to the first subpixel value and the first compensation temperature value to obtain a first compensation value, generate a first drive value according to the first subpixel value and the first compensation value to drive a first pixel structure located at the down-sampling position, and update the lookup table according to the first drive value,
• wherein a second area is adjacent to the first area, a third area is adjacent to the first area and the second area,
• wherein the temperature compensation circuit is configured to calculate a second drive value at a down-sampling position of the second area, and calculate a third drive value at a down-sampling position of the third area,
• for a second pixel structure within a range formed by the down-sampling positions of the first area, the second area, and the third area, the temperature compensation circuit is configured to interpolate a difference according to the first drive value, the second drive value and the third drive value, and adjust a subpixel value corresponding to the second pixel structure according to the difference, wherein the second pixel structure is different from the first pixel structure,
• wherein the temperature compensation circuit is configured to change the down-sampling positions of the first area, the second area, and the third area for different frames.
