Problems solved by technology

[0017] According to the above description, the power control device of the PDP TV manufactured by the prior art obtains power from the VS power delivery device, the VA power delivery device, the Vsetup power delivery device, and the Vsc power delivery device. When the current passes through the VS power delivery device, due to Drive mode, if the current amplitude is too large, the change speed will be too fast, which will cause the screen to flicker when driving the PDP

Embodiment Construction

[0024] figure 2 It is the front view of the PDP power control device of the present invention.

[0025] According to the present invention PDP power supply control device such as figure 2 As shown: the standby module, that is, when the screen is not displayed, in order to be able to respond to the start command input by the user through the remote controller, the standby power supply 101 supplies power to the necessary components; the microprocessor 102 controls the overall system and outputs power control signals; After receiving the common AC power of input, the power controller 105 of supplementary power; After receiving the delivery voltage of the power controller 105, deliver to the PDP module 110 the Vs power delivery device 106 that drives the maintenance electrode to maintain the voltage; the output of the power controller 105 After the voltage is transformed, in order to drive the PDP module (110) address electrode, the Vsc power delivery device 107 that provides t...

Abstract

The power supply controller for plasma television consists of exchanger to control the on-off of the AC power supply; power controller to complementing the power of the AC power supply applied via the exchanger; microprocessor controlling the exchanger to power the power controller; the first and the second power supply feeders applying the work voltage to electrodes of the PDP module after obtaining voltage from the power controller; and the third and the fourth power supply feeders applying the work voltage to electrodes of the PDP module after obtaining voltage from the first power supply feeder. Feeding the maintaining electrode of the PDP module with distributed current can reduce the variation of current to the maintaining electrode and prevent frame flash in advance.

Description

technical field [0001] The invention relates to a power control device, in particular to a power control device for a PDP TV. Background technique [0002] TV is an audio-visual device that takes the signal transmitted by the TV station, selects and demodulates the audio-visual signal according to the channel selected by the user, separates it into audio-visual signals, and processes the related audio-visual signals and then plays them through the screen and speakers. [0003] Among such TVs, LCDs and PDPs are used in pursuit of high-definition and large screens, such as widely used CRTs. [0004] In particular, TVs using PDP are ultra-thin in structure compared with the original CRT, and have stronger bendability than LCDs to meet the technical requirements of TVs, and have the characteristics of being able to be placed on the wall , as a new type of TV, is becoming popular. [0005] However, since a high voltage is required to start a PDP TV, the control of the structure...
