Abstract
A micro-display device comprises a silicon substrate in which a plurality of gate lines, a plurality of data lines, a plurality of emission signal lines, and a plurality of subpixels are disposed; a gate driver circuit disposed on a first side of a pixel array to drive the plurality of gate lines; an emission driver circuit driving the plurality of emission signal lines and disposed on a second side of the pixel array different from the first side of the pixel array where the gate driver circuit is disposed; a data driver circuit disposed on a third side of the pixel array to drive the plurality of data lines; a memory storing duty data regarding duty ratios of an emission signal applied to the plurality of emission signal lines; and a control circuit controlling signals applied to the gate driver circuit, the data driver circuit and the emission driver circuit, wherein the control circuit is set to have different emission times with respect to subpixels connected to the plurality of emission signal lines according to the duty data stored in the memory.
