## Abstract

The disclosure provides an OLED display device and a driving method thereof. The OLED display device includes an OLED display module, a driving module, and a system module, and the driving module includes a display driving module and a human eye recognition module; the system module generates display data based on an image, the display driving module drives the OLED display module to display according to the data, and the human eye recognition module senses a human eye's focus area and gives feedback information to the system module; when the human eye recognition module senses the human eye's focus area, information thereof is fed back to the system module, the system module determines the focus and non-focus areas according to the information, then the display driving module turns off all or part of predetermined sub-pixels in the non-focus area. The disclosure can prolong the lifetime of the OLED display device.

## Claims

### Claim 1

An OLED display device, comprising
