Patent ID: 11955086
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 11:
12. A display device comprising:
a silicon substrate;
a semiconductor layer provided on the silicon substrate and including a pixel circuit;
an image sensor provided on the silicon substrate and activated based on an imaging instruction;
light emitting elements disposed on the semiconductor layer and electrically connected to the pixel circuit; and
a display driver electrically connected to the pixel circuit to control the pixel circuit and to control image luminance of an imaging frame in which the image sensor is activated,
wherein the display driver comprises:
a controller generating black image data corresponding to the imaging frame based on the imaging instruction;
a data driver converting the black image data into an analog data signal and supplying the data signal to the light emitting elements;
a memory temporarily storing input image data;
an image analyzer counting black image data of the input image data in units of frames based on the imaging instruction; and
an imaging frame determiner determining the imaging frame based on a counting value of the black image data and generating an image sensor activation signal.
