Embodiment Construction

[0027] In the following, examples of various implementations are illustrated in the drawings and described further below. The suffixes "module" and "unit" of components used in the following description are assigned or mixed in consideration of ease of writing the description, and they have no unique meaning or role by themselves.

[0028] A display device according to an embodiment of the present disclosure is, for example, a smart display device in which a computer support function is added to a broadcast receiving function. In a display device that basically has a broadcast receiving function, an Internet function and the like are added. Thus, the display device may include an easy-to-use interface such as a writing input device, a touch screen, or a spatial remote control. With the support of wired or wireless Internet capabilities, the display device can connect to the Internet and computers and perform functions such as e-mail, web browsing, banking or gaming. In order...

Abstract

An organic light emitting diode display apparatus includes a display panel, a discharge circuit configured to discharge a voltage if the display panel is driven for more than a predetermined time andthe supply of power to the display panel is interrupted, and a processor configured to, if the power is supplied, determine whether a cooling time required for afterimage compensation of the display panel is satisfied, and if the cooling time is satisfied, perform the afterimage compensation of the display panel.

Description

technical field [0001] The present disclosure relates to an organic light emitting diode (OLED) display device, and more particularly, to an OLED display device capable of measuring a turn-off time of a display panel even if power supply is interrupted. Background technique [0002] Recently, various types of display devices have appeared. Among these display devices, organic light emitting diode (OLED) display devices are widely used. Since the OLED display device is a self-luminous device, it has lower power consumption and can be manufactured thinner than a liquid crystal display (LCD) requiring a backlight. In addition, the OLED display device has a wide viewing angle and a fast response time. [0003] A common OLED display device includes red (R) subpixels, green (G) subpixels, and blue (B) subpixels as one unit pixel, and displays one image with various colors through the three subpixels. [0004] In the case of an OLED display device, if a fixed image (for example,...
