Abstract: A display device includes a display panel including a pixel, a temperature sensor which senses a temperature of the display panel and outputs the temperature of the display panel as a sensing temperature, a first compensation part which receives a gate-source voltage sensed in the pixel as a sensing voltage and compensates for the sensing voltage by a change amount of the gate-source voltage corresponding to a difference value between a reference temperature and the sensing temperature, and a second compensation part which compensates for data to be applied to the pixel by comparing a compensated sensing voltage with an initial gate-source voltage.

Abstract: A display apparatus includes a display panel, a panel driver, a light source part, and a light source driver. The display panel includes a first sub-pixel having a first primary color, a second sub-pixel having a second primary color, and a third sub-pixel having a white color. The panel driver drives the first, second, and third sub-pixels. The light source part provides the display panel with light. The light source part includes a first light source and a second light source. The first light source emits the light having a mixed color of the first primary color and the second primary color. The second light source emits the light having a third primary color. The first and second light sources are alternately turn on in one frame period. A turn-on order of the first and second light sources is changed by a unit of at least one frame period.
