Display device and method of driving the same

摘要

Provided is a display device. The display device includes: a pixel including an emissive element circuit, a reflective element circuit, and a switch transistor selecting one of the emissive element circuit and the reflective element circuit; an illumination sensor generating an illumination information signal according to an illumination of an external light source by detecting the external light source; and a controller generating control signals for driving the pixel according to pixel data, wherein the controller generates a light signal controlling the switch transistor by referencing the illumination information signal.

1. A display device comprising:
a pixel including:
an emissive element circuit;a reflective element circuit;a first transistor serving as a switch transistor that selects one of the emissive element circuit and the reflective element circuit;a second transistor that is connected to the reflective element circuit, and is turned on or off in response to a scan signal when the first transistor is turned on;a third transistor that is turned on or off in response to a scan signal when the first transistor is turned off, the reflective element circuit being driven in response to a data signal through the second and third transistors; anda fourth transistor that is connected to the emissive element circuit, the emissive element circuit being driven in response to an emissive signal through the fourth transistor; an illumination sensor that generates an illumination information signal based on an illumination from an external light source; and a controller that generates control signals including the scan signal, the data signal, and the emission signal, for driving the pixel, and generates a light signal controlling the switch transistor by referencing the illumination information signal.
