Display device and driving method thereof

Abstract

The invention provides a display device and a driving method thereof, relates to the technical field of display, and solves the problem that the conventional display panel is difficult to realize high resolution by changing a base plate. The display device comprises a display panel, a light modulator, a first driving module and a second driving module, wherein the display panel comprises a plurality of pixels; each pixel comprises n virtual pixels; the light modulator is arranged on the light outlet side of the display panel, and comprises a plurality of light modulating units corresponding to the pixels; each light modulating unit comprises n light modulating areas corresponding to the virtual pixels respectively; a one-frame image comprises n sub-frame images; the first driving module is used for driving the display panel to sequentially display the continuous n sub-frame images in the one-frame image; the second driving module is used for driving the n light modulating areas of the light modulating unit to be light transmitting areas in n sub-frame images sequentially and for driving the other (n-1) light modulating areas to be light shading areas, wherein n is a positive integer greater than or equal to 2.

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] In the field of electronic display, the pursuit of clearer images has always been the goal, which is mainly achieved by increasing the display resolution. Display resolution is the precision of the displayed image, which refers to the number of pixels that the display can display. The more pixels a monitor can display, the finer the picture, and the more information can be displayed in the same screen area. [0003] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display panel is favored because of its self-luminous display, and being made of organic materials, so that it can be rolled, folded, etc. The light-emitting principle of OLED display panels is: an organic light-emitting layer is deposited between two electrodes. After the two electrodes are powered on, holes and ele...

Problems solved by technology

[0004] However, since the organic light-emitting layer of OLED is generally prepared by mask evaporation, that is, the organic light-emitting layer is formed through a mask, and controlled by the precision of the mask, the organic light-emitting layer cannot be deposited in a small area, that is, through a mask The pixel electrode formed by the film plate has a large area, which makes it unable to meet the requirements of high display resolution products
