Abstract
The present disclosure relates to a display substrate, a display device, and a control method thereof. The display substrate includes a plurality of pixels, each of which includes a first sub-pixel, a second sub-pixel, a third sub-pixel, and a fourth sub-pixel. The first sub-pixel, the second sub-pixel, and the third sub-pixel have different light emission colors. The fourth sub-pixel has the same light emission color as the first sub-pixel. The first sub-pixel, the second sub-pixel, the third sub-pixel, and the fourth sub-pixel all emit light, in a case where an ambient temperature is less than a first threshold. The second sub-pixel and the third sub-pixel both emit light, and one of the fourth sub-pixel and the first sub-pixel emits light, in a case where the ambient temperature is greater than or equal to the first threshold.
