    摘要： A pixel array, a display apparatus and a fine metal mask are provided. The pixel array includes first basic pixel units in odd-numbered rows and second basic pixel units in even-numbered rows; each first basic pixel unit includes first, second and third sub-pixel groups sequentially in a row direction; each second basic pixel unit includes the third, first and second sub-pixel groups sequentially in the row direction; the first, second and third sub-pixel groups include two first, two second and two third sub-pixels in a column direction, respectively; the first, second and third sub-pixels have different colors; the first and second basic pixel units in the even-numbered and odd-numbered rows are aligned in the column direction, respectively; in the first and second basic pixel units in two adjacent rows, the third sub-pixel groups in the two rows are staggered with each other in the row direction.

    摘要： A driving method includes, at a first display brightness value, inputting a pulse-width modulation signal with a duty ratio of X, and controlling a light-emitting driving current of a sub-pixel unit to be M, wherein X and M are obtained according to a first modulation rule; and at a second display brightness value, inputting the pulse-width modulation signal with a duty ratio of Y1, and controlling the light-emitting driving current of the sub-pixel unit to be N1, wherein the first display brightness value is greater than the second one, wherein, when the duty ratio and the light-emitting driving current corresponding to the second display brightness value are obtained according to the first modulation rule, the duty ratio corresponding to the second display brightness value is Y2, the light-emitting driving current corresponding to the second display brightness value is N2, Y1 is smaller than Y2, and N1 is greater than N2.

    摘要： 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.
