Abstract
According to an aspect of the present disclosure, a display device includes a display panel in which a plurality of pixel groups is defined; one PAM circuit disposed in each of the plurality of pixel groups; a plurality of PWM circuits which is disposed in each of the plurality of pixel groups and is connected to one PAM circuit; a plurality of light emitting diodes which is disposed in each of the plurality of pixel groups and is connected to the plurality of PWM circuits. The plurality of PWM circuits is connected to an output terminal of one PAM circuit in parallel in each of the plurality of pixel groups. Accordingly, the plurality of PWM circuits shares one PAM circuit to reduce the number of overall transistors and simplify the structure of the display device.
