Patent Images

1. display device, comprise the display part, wherein with matrix form arrange pixel, with the invisible scanning cycle provide selection with the selection signal of luminous pixel to the sweep trace of described pixel, the data line of vision signal to described pixel is provided, described vision signal is provided to its driving transistors, described pixel has according to the pixel of the luminous light-emitting component of the magnitude of current and according to vision signal control and is applied to the image element circuit of the electric current of described light-emitting component, and described display device also comprises:

  • The gamma conversion part, it changes described vision signal makes it have gamma characteristic;

    AndThe transistor controls part, it controls transistorized I-E characteristic, makes the gamma characteristic of the signal partly changed by described gamma conversion become linear characteristic when multiply by transistorized I-E characteristic.
