Description

Display screen drive box for flat-plate television set

Technical field

The utility model relates to panel TV set and display technology field, relates in particular to the display screen drive box for flat-plate television set of liquid crystal TV set, plasma TV and emission natural daylight diode TV machine.

Background technology

At present, panel TV set has entered the family of ordinary people, the classic flat-plate television set is because display area is big, the streamline production and assembly finish, and only to carry out 2 to 8 hours normal temperature usually aging, and high low temperature aging only is suitable for a spot of sampling Detection, all do not carry out high low temperature aging when producing, stay more multiple faults hidden danger in the time of will using for the end user just because of panel TV set.

The back side that the digital and analogue signals reception disposable plates of traditional panel TV set and power panel are assemblied in display screen, and covered by the back cover of television set, and the failure rate of digital and analogue signals reception disposable plates, power panel, remote control panel and keypad accounts for more than 90% of panel TV set, the repair rate of panel TV is very high, uses after 1 year out of order probability very big.When receiving disposable plates, power panel, remote control panel and keypad, digital and analogue signals breaks down, just need take complete machine apart maintenance, also need the professional and technical personnel that on-site maintenance is provided, and the panel TV set of selling on the market at present, the in-company technical staff that has only who has could keep in repair the panel TV that our company makes.This not only makes troubles to the user, and increases maintenance cost.

Summary of the invention

The utility model is at above-mentioned prior art present situation, provide a kind of solution user maintenance cost height, can not HardwareUpgring, the display screen drive box for flat-plate television set of complete machine manufacturing enterprise product repair rate height, production capacity is low and after service cost is high problem.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this driving box box body independently is installed in outside the panel TV set casing, the digital and analogue signals that panel TV set is installed in the box body receives disposable plates, DVD player, harddisk memory, keypad and remote control panel, wherein DVD player, harddisk memory, remote control panel and keypad are connected digital and analogue signals reception disposable plates through signal connecting line respectively.

Drive in the box box body power panel also is installed, this power panel connects described digital and analogue signals through signal connecting line and receives disposable plates.

Drive in the box box body surround sound power board also is installed, this surround sound power board connects described digital and analogue signals through signal connecting line and receives disposable plates.

The utility model compared with prior art, the critical component of concentrated complete machine fault point more than 90% is shifted out design in the TV shell to be assembled in the display screen drive box for flat-plate television set, very strong compatibility and versatility are arranged, drive the liquid crystal flat-panel used as television display screen drive box of large-sized liquid crystal display, only need the simple software that upgrades the inside just can directly drive undersized LCDs, the liquid crystal flat-panel used as television display screen drive box that the back produces can directly replace the previous unidimensional liquid crystal flat-panel used as television display screen drive box of producing; Because the plasma flat-screen televisions machine is not with comprising power panel in the display screen drive box, its compatibility and versatility are stronger than liquid crystal flat-panel used as television display screen drive box.Although display screen drive box for flat-plate television set has been concentrated the fault point of complete machine 90%, it only accounts for 10% of complete machine cost, and volume is quite as common DVD player size; Because volume is little, assembling is produced easily, uses the dummy load that is equivalent to display screen to replace the true load of display screen of display screen drive box for flat-plate television set, and the complete machine of equivalence all carries out high low temperature aging flow process in the time of just realizing production, thereby greatly reduces repair rate.This just provides bigger advantage for the after-sale service of complete machine manufacturing enterprise, has reduced to aim at the stock of after-sale service with components and parts, and after-sale service is more oversimplified, and the after-sale service response time shortens, and after service cost greatly reduces; For the user has saved maintenance cost, prolonged the life cycle of panel TV set, saved social resources effectively.
