Abstract
A display device includes a display panel and a control system. The display panel includes multiple pixel groups. Each pixel group includes several sub-pixel circuits and a pulse width modulation (PWM) circuit. The sub-pixel circuit receives pulse amplitude modulation (PAM) data and controls the luminous intensity. The PWM circuit receives PWM data and controls the luminous time. The control system is used to receive image information that includes current grayscale values of the sub-pixel circuits; to establish the PWM data based on the current grayscale values through a first look-up table; to convert the current grayscale values to target grayscale values through a second look-up table, in which the target grayscale values corresponds to the PAM data; and to output image information including the PWM data and the target grayscale value.
