Abstract: A display device can include a display panel having sub pixels configured to emit light of different colors, a data driver configured to output a data voltage to the sub pixels via data lines, and a timing controller configured to output power control signals for controlling a driving current which drives the data driver. The data driver can include source driving integrated circuits, each including power control circuits configured to generate the driving current in accordance with each of the power control signals, and amplifiers configured to be applied with the driving current to output the data voltage to each of the data lines.

Abstract: Embodiments of the disclosure concern display devices. The voltage line for supplying driving voltage to the cathode electrode of the light emitting element in the subpixel and the voltage line for supplying voltage for initializing the subpixel are integrated together. This allows for use of fewer voltage lines in the active area, along with easier arrangement of the voltage lines. The wire resistance may be reduced by adjusting the width of the voltage lines. The reduction in wire resistance may decrease brightness deviation or increase the aperture ratio or transmittance of the subpixel, thus allowing the display device higher light emission efficiency or transmittance.

Abstract: A display device includes a light shield layer disposed on a substrate, a first buffer layer disposed on the light shield layer, a silicon layer disposed on the first buffer layer and including an undoped area and a doped area, a second buffer layer disposed on the silicon layer, and a thin film transistor disposed on the second buffer layer. The doped area is disposed at a position overlapping with the light shield layer. Accordingly, the display device can realize a wide range of grayscale representation and a fast on-off operation by adjusting the S-factor of a specific thin film transistor.
