Claim 9:
10. The display screen aging compensation method according to claim 2, wherein the average brightness value DBV of the at least one display area within the usage time t is obtained by performing at least one of:
obtaining a current brightness value DBV_c of the display area when obtaining the display data; and
keeping, in response to the current brightness value DBV_c being 0, the average brightness value DBV of the at least one display area at an average brightness value DBV_aver that is obtained before the display data is obtained; or
determining, in response to the current brightness value DBV_c being a non-zero value, the average brightness value DBV according to DBV=(t*60*DBV_aver+T*DBV_c)/(t*60+T), wherein a unit of the usage time t is hour, and a unit of a sampling period P is a minute.
