In the present embodiment, in the first sequential adjustment instruction that display terminal inputs according to user, after completing the synchronous process of backlight scanning sequence and picture display and control sequential, or after display terminal does not receive the first sequential adjustment order persistence preset duration, the picture display and control sequential that display terminal preserves according to this display terminal of current time further, Alternation Display the 2nd test pictures in the display area of this display terminal, adjust with the On/Off sequential to the supporting 3D glasses of display terminal, the picture display and control sequential current with simultaneous display terminal and the On/Off sequential of 3D glasses, thus optimize the 3D visual and sound effects of display terminal further, avoid the problem that crosstalk occurs.
Further, eliminate on the basis of method first embodiment of the three-dimensional crosstalk of display terminal in the present invention, propose to eliminate method the 3rd embodiment of the three-dimensional crosstalk of display terminal, in the third embodiment, first test pictures to be background be preset dead color and background are arranged at intervals with the picture in multiple brightness contrast region with identical gray scale, brightness contrast region has different gray scales from background
When the luminance difference that observations is any two brightness contrast regions is greater than predeterminable level, user inputs described first sequential adjustment instruction.
Display terminal is when the three-dimensional crosstalk adjustment instruction receiving user's input, first the display area background color of display terminal is adjusted to preset dead color (this preset dead color is the color that grey, black or coffee-like geometric ratio countenance are dense or dark), then in the display area of preset dead color, show the picture that multiple interval arranges and has the brightness contrast region of identical gray scale, in addition, the color in this brightness contrast region can be preset light tone (this preset light tone is white or that light green geometric ratio countenance is shallow or bright color).
Preferably, top area in the display area of preset dead color and bottom section show multiple interval and arrange and be the brightness contrast region of preset light tone. owing to the central region of the display area of display terminal is relatively bright, the top area and the bottom section brightness that are positioned at central region both sides are relatively dark, namely the display area brightness of display terminal is that (middle part is bright in normal distribution, top and bottom are dark), brightness contrast region is separately positioned on top area and the bottom section of display area, there is good representativeness, if the brightness between the brightness contrast region of top area and the brightness contrast region of bottom section is substantially identical, then can all regional luminances of basic confirmation display terminal display area substantially identical, thus by improving, in the top area of the display area of preset dead color and the multiple spaced brightness contrast region of bottom section display, the accuracy and promptness of eliminating crosstalk.
In the present embodiment, when display terminal carries out three-dimensional crosstalk adjustment, the display area background color of display terminal is adjusted to preset dead color, brightness contrast region is preset light tone, make the colouring discrimination of brightness contrast region and display area background color distinct, be conducive to the difference of the brightness in the more each brightness contrast region of user, thus be conducive to user to input the first correct sequential adjustment instruction, for display terminal according to the first correct sequential adjustment instruction, the backlight scanning sequence of adjustment display terminal and/or picture display and control sequential, with this backlight scanning sequence synchronous and picture display and control sequential, thus it is more accurate, eliminate the cross-interference issue of display terminal efficiently.
In addition, eliminate on the basis of method the 2nd embodiment of the three-dimensional crosstalk of display terminal in the present invention, the picture being arranged at intervals with multiple brightness contrast region with identical gray scale in first test pictures to be background be preset dead color and background, brightness contrast region has different gray scales from background
