Abstract
The present application relates to a method for compensating temperature and a display apparatus. The method for compensating temperature may include: setting an on-pulse width of an emission signal according to luminance of pixels based on optical compensation; generating first and second linear function graphs by measuring luminance according to the on-pulse width of the emission signal set at first and second temperatures; generating a target linear function graph relating the on-pulse width of the emission signal set at a target temperature and luminance based on the first and second linear function graphs; and adjusting the on-pulse width of the emission signal set based on the target linear function graph.
