Display device
A display device is provided. The display device includes a panel, a memory, and a controller. The panel includes multiple pixels. The memory includes a first section and a second section. The memory stores an aging record table. Multiple brightness attenuation values recorded in the aging table are respectively divided into multiple first portion attenuation values and multiple second portion attenuation values. The first section stores the first portion attenuation values. The second section stores the second portion attenuation values. The controller includes an update circuit and a compensation circuit. The controller is coupled to the panel and the memory. The update circuit receives gray values displayed by the pixels to update the aging table. The compensation circuit reads the first portion attenuation values from the first section so as to perform an aging compensation on the pixels.
