[0023]As described above, according to the present disclosure, an LED display device allows expressing the gray scale more precisely. In addition, according to the present discl

Problems solved by technology

However, although the above-described display devices have advantages of high resolution, they have disadvantages that enlargement thereof is difficult.
For example, large OLED display devices developed so far are just 80 inches (approximately 2 m) to 100 inches (approximately 2.5 m), so it is not suitable for producing large display devices having a width of 10 m or more.

Example

[0034]FIG. 1 is a diagram illustrating the configuration of a display device according to an embodiment.

[0035]Referring to FIG. 1, a display device 100 may include a driving device 110 and a panel 120.

[0036]The panel 120 may have a plurality of pixels P arranged in a matrix in a first direction (e.g., a horizontal direction in FIG. 1) and a second direction (e.g., a vertical direction in FIG. 1).

[0037]At least one light-emitting diode (LED) may be disposed in each pixel P, and the brightness of the pixel P may be determined according to the brightness of the LED.

[0038]Driving lines DL and scan lines SL may be arranged on the panel 120. The driving lines DL may connect one sides of the pixels in the second direction, and the scan lines SL may connect the opposite sides of the pixels in the first direction. For example, an anode of the LED disposed in the pixel P may be electrically connected to the driving line DL, and the cathode of the LED may be electrically connected to the scan lin

Abstract

The present disclosure relates to an LED driving technology. According to the present disclosure, it is possible to increase the fineness of the gray scale without increasing a frequency of a clock by combining a plurality of driving current sources to generate a driving current supplied to one driving line.
