Abstract

The invention provides a method for acquiring an overdrive lookup table. The method comprises the following steps: step 202, acquiring a first testing frame image and a second testing frame image need to be played in sequence, wherein pixel gray levels of the testing frame images are a first gray level and a second gray level in a designated area; step 204, carrying 3D display by utilizing a real-time overdrive valve; step 206, identifying the first testing frame to be a left-eye image or a right-eye image, and acquiring comprehensive brightness and image brightness; and step 208, storing the real-time overdrive valve to the overdrive lookup table if the comprehensive brightness is matched with the image brightness; and if the comprehensive brightness is not matched with the image brightness, returning to the step 204. Correspondingly, the invention also provides a device for acquiring the overdrive lookup table and a display device. Through the technical scheme, the suitable overdrive value can be rapidly obtained so as to promote the picture display effect.

Description

technical field [0001] The invention relates to the field of overdrive control, in particular, an acquisition method, an acquisition device and a display device of an overdrive value lookup table. Background technique [0002] A 3D display must provide appropriate images for the left eye and right eye of a person respectively, in order to present a stereoscopic image in the human brain. In the stereoscopic display technology, the currently more mature one is the time-series stereoscopic display, which means that the left-eye and right-eye images are displayed alternately in time series, and the viewer's eyes can alternately see the left-eye image and the right-eye image, for example , the use of shutter glasses, combined with a monitor that alternately displays left-eye and right-eye images, allows the audience to see a three-dimensional picture. Since the liquid crystal display is a sustaining type display, each pixel on the liquid crystal display continuously displays the...
