Abstract
The invention provides a backlight module device and a control method thereof as well as a television (TV). Backlight modules of segmented regions are respectively used for controlling corresponding display areas, and the liquid crystal molecules of liquid crystal glasses lenses of a pair of shutter type 3D glasses are matched for opening backlight within the stable-state time period; different supply currents are set for the backlight modules of the different regions, the high backlight supply current is set when high backlight brightness is needed, and the high backlight brightness can be used for compensating the display brightness of the liquid crystal molecules which are not positioned in the stable-state area. The different backlight supply currents are set, so that the technical problem that the display brightness of a 3D liquid crystal display (LCD) screen is not uniform can be solved, the brightness uniformity index of the 3D LCD screen is improved, and the 3D display effect is improved.
Description
[0001] This application is a divisional application of the Chinese invention patent application 201210315647.4 filed on August 30, 2012 under the title "A backlight module device and control method, television". Technical field [0002] The present invention relates to the technical field of audio and video, in particular to a backlight module device and a control method, and a television. Background technique [0003] With the development of 3D display technology, there are many technical solutions that can realize 3D display. According to different display technologies, there are mainly two types of glasses-type 3D display and naked-eye 3D display. Among them, the glasses-type 3D display technology mainly include: Shutter 3D display technology, polarized light 3D display technology. [0004] Among them, the evaluation index of shutter 3D display technology includes at least anti-crosstalk performance. In the prior art, in order to solve the crosstalk problem, a liquid crystal scr...
