Embodiment Construction

[0032] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0033] figure 1 is a flow chart of the control method of the plasma display according to the first embodiment of the present invention, such as figure 1 As shown, the method includes the following steps S102 to S104:

[0034]Step S102: Divide the display screen of the plasma display into blocks to obtain multiple sub-pictures. For example, a WXGA high-definition module can divide the entire display screen into A*B blocks, such as figure 2 As shown, the display screen of the plasma display is divided into 16*9 image blocks to obtain 144 sub-pictures.

[0035] Step S104: Detect whether each sub-picture in the plurality of sub-pictures is still, so as to figure 2 Take the display screen of t...

Abstract

The invention provides a plasma display screen and a method and device for controlling the same. The method comprises the following steps: dividing the display screen of the plasma display screen into a plurality of sub-screens, detecting to find whether the sub-screens are static or not, and reducing the brightness of the static sub-screens if some or all of the sub-screens are static. In the invention, because the whole display screen of the plasma display screen is divided into blocks, the sub-screens are detected to find whether the sub-screens are static or not, and the brightness of the static sub-screens is reduced, the residual images can be eliminated completely, and the quality of the moving images can not be affected.

Description

technical field [0001] The invention relates to the field of displays, in particular to a plasma display and a control method and device thereof. Background technique [0002] The alternating current plasma display (AC-PDP) adopts the multi-subfield display technology to realize the multi-gray-level display of images. When the PDP module adopts sub-field separation technology (ADS) to realize the picture display process, its gray level performance is realized by means of sustaining pulse PWM modulation. The main mechanism is to activate the ternary gas of He+Ne+Xe in the discharge unit of the module to generate ultraviolet rays to excite the phosphor powder to emit red (R), green (G) and blue (B) three-color light through ADS driving to achieve color grayscale show. [0003] During the display process, the MgO layer of the upper substrate and the phosphor layer of the lower substrate are affected by ultraviolet rays. As the screen pattern changes, the contribution of MgO a...
