The method includes: obtaining each driving voltage corresponding to each grayscale signal of the self-luminous display (S30); determining, according to intervals to which each driving voltage belongs, each preset driving function corresponding to each driving voltage (S31); determining each first driving current corresponding to each driving voltage according to each preset driving function (S32); detecting each second driving current of pixel units of the self-luminous display in case of being driven at each driving voltage (S33); comparing the first driving current with the second driving current, and determining compensating voltages corresponding to each grayscale signal according to each preset driving function, and differences between each first driving current and each second driving current (S34). The grayscale compensating method and apparatus for the self-luminous display and the self-luminous display device utilize different driving functions for different grayscale signals to determine the compensating voltages, so that the driving voltages of each grayscale can be better compensated, thus realizing brightness and chrominance uniformities of each grayscale of the self-luminous apparatus and the display device.

Each sub-pixel circuit(P1, P2) comprises five switch units(T1, T2, T3, T4, T5), a driving unit(DT), an energy storage unit(C) and an electroluminescent unit(L). The two sub-pixel circuits (P 1, P2) are connected to the same operating voltage line(Vdd), the same data voltage line(Vdata), the same first scanning signal line(Scan[1]), and the same third scanning signal line(Scan[3]), and are connected to different second scanning signal lines(Scan[2]), so that in the pixel circuit, the operating current flowing through the electroluminescent unit(L) is not affected by the threshold voltage of the corresponding driving transistor, completely solving the problem of non-uniformity in the display brightness due to drifting of the threshold voltage of the driving transistor. Meanwhile, a compensation circuit is used to drive two pixels(P1, P2), and two adjacent pixels(P1, P2) share a plurality of signal lines, thus reducing the number of signal lines for the pixel circuits in a display apparatus, decreasing the pixel pitch, and increasing the pixel density. Also provided is a display apparatus using the pixel circuit.
