Embodiment Construction

[0026] 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.

[0027] image 3 is a flowchart of a control method of a plasma display according to an embodiment of the present invention, such as image 3 As shown, the method includes the following steps S102 to S108:

[0028] Step S102: Detect the load of the display screen image of the plasma display, wherein the larger the gray scale of the display screen image is, the greater the load is.

[0029] Step S104: Determine whether the load of the displayed image is greater than a preset value, and the preset value is selected according to different plasma displays.

[0030] Step S106: When the load of the displayed image is greater than a preset value, control the energy recovery rise time of the drive ci...

Abstract

The invention discloses a plasma display as well as a control method and device thereof. The control method comprises the following steps of: detecting a load of an image in a display picture of the plasma display; and judging whether the load of the image in the display picture is more than a pre-set value; if so, controlling energy recovery and rising time in a discharging maintenance stage of a drive circuit of the plasma display to be first pre-set time; otherwise, controlling the energy recovery and rising time in the discharging maintenance stage of the drive circuit of the plasma display to be the second pre-set time, wherein the first pre-set time is less than the second pre-set time. In the invention, the energy recovery and rising time in the waveform drive maintenance stage is adjusted according to the size of the load of the image in the display picture of the plasma display, thereby improving the discharge of the plasma display in the maintenance stage, improving the efficiency of the drive circuit, reducing the power consumption of the circuit and improving the luminous efficiency of the plasma display.

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] Color alternating current plasma (AC-PDP) is developed based on the basic principle of gas discharge, and the ultraviolet light emitted by gas discharge excites phosphors to emit light to realize display. At present, the three-electrode surface discharge type AC-PDP is the most competitive type of PDP. For this kind of AC-PDP, addressing and display separation (ADS) technology is mostly used to realize grayscale display, that is, a TV field is divided into 8 or 10 or 12 sub-fields that emit light successively, each sub-field is composed of a preparation period, an addressing period and a maintenance period, and a 256-level grayscale display can be realized through an appropriate combination of sub-fields. [0003] In the three-electrode surface discharge type AC-PDP, the three electrodes are orthogona...
