Display device and driving method thereof

Abstract

The invention discloses a display device and a driving method thereof for realizing 3D display without increasing a cylindrical mirror or a parallax barrier device and reducing the production cost. The display device comprises a black and white liquid crystal display panel, an organic light emitting display panel and a control unit for controlling the organic light emitting display panel to emit light, wherein the black and white liquid crystal display panel and the organic light emitting display panel are attached together; the organic light emitting display panel serves as a backlight source for the black and white liquid crystal display panel and comprises a plurality of pixels; each pixel comprises a red sub pixel, a green sub pixel and a blue sub pixel; the black and white liquid crystal display panel comprises a plurality of pixel units and each pixel is corresponding to at least one pixel unit; and the control unit is used for dividing a frame of display time at least into a first time period, a second time period and a third time period, only the red sub pixel is controlled to emit light in the first time period, only the green sub pixel is controlled to emit light in the second time period, and only the blue sub pixel is controlled to emit light in the third time period.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a driving method thereof. Background technique [0002] Thin Film Transistor Liquid Crystal Display (TFT-LCD) is currently the mainstream product in the display field, accounting for most of the market share. With the development of technology, more display functions have been added to LCD display, such as three-dimensional (3D) display, which is the most widely used in the existing technology, and 3D display is more realistic, with a sense of scene and entry. [0003] At present, 3D display technology mainly includes glasses-free and glasses-free glasses-free. Glasses-wearing 3D display technology has developed very maturely, but it cannot free us from the shackles of special glasses, which makes its application range and comfortable use The naked-eye 3D display technology has attracted more and more people's attention because it does not need to w...

AI Technical Summary

Problems solved by technology

[0005] To sum up, when the existing technology realizes naked-eye 3D display, it is necessary to add a cylindrical mirror or a slit grating device, and the production cost is high, and if a cylindrical mirror is used for imaging at a large viewing angle, the aberration of the cylindrical mirror will seriously affect the 3D Imaging Quality
