Abstract
A display device includes a display panel including a pixel, a data driver providing a data voltage to the pixel, a gate driver providing a gate signal to the pixel, and a controller controlling the data driver and the gate driver. The pixel includes a first sub-pixel including a first light emitting element, and a second sub-pixel including multiple second light emitting elements.
Claims16
A display device comprising:
- a display panel including a pixel;
- a data driver configured to provide a data voltage to the pixel;
- a gate driver configured to provide a gate signal to the pixel;
- and
- a controller configured to control the data driver and the gate driver,
- wherein the pixel includes:
- a first sub-pixel including a first light emitting element;
- and
- a second sub-pixel including:
- a plurality of second light emitting elements emitting blue light, and
- a plurality of light conversion patterns having different light conversion functions and converting the emitted blue light into white light, and
- wherein the display panel is driven in one of a plurality of driving modes that independently modulate emission time and driving current for the first sub-pixel and the second sub-pixel as a function of grayscale.
