Description
Technical field
The present invention relates to liquid crystal display display field, especially a kind of high-definition liquid crystal screen framework.
Background technology
There is different modes in liquid crystal panel factory for the shipment of TV liquid crystal module.Current TV liquid crystal panel market is in semi-manufacture mode, and the liquid crystal display (Open Cell) namely not installing backlight is favored gradually.Main cause is to reduce costs, and selects buying not replace panel finished product containing the semi-manufacture of backlight.This liquid crystal display (Open Cell) is the semi-manufacture assembled with original papers such as liquid crystal panel, color filter and Polarizers.Shipment, to after television manufacturer, can purchase backlight more separately, and its purchase cost, compared with finished panel, can significantly reduce.
Summary of the invention
The invention provides a kind of high-definition liquid crystal screen framework, comprise one block of sequential control plate and 2 pieces of source plates, 2 pieces of grid boards, 14 source electrodes-cover brilliant film, 8 grids-cover brilliant film, thin film transistor liquid crystal display screen; Sequential control plate is connected with 2 pieces of source plates by flexible connector, and 2 pieces of source plates are by 14 source electrodes-cover brilliant film to be connected with corresponding thin film transistor liquid crystal display screen; 2 pieces of grid boards are by 8 grids-cover brilliant film to be connected with corresponding thin film transistor liquid crystal display screen; 2 pieces of source plates are connected by splicing ear with between 2 pieces of grid boards.
Sequential control plate comprises Low Voltage Differential Signal load module, time-sequence control module, power module and gamma module; Low Voltage Differential Signal load module input Low Voltage Differential Signal and power supply, Low Voltage Differential Signal is converted to Miniature low voltage differential signal and flows to source electrode-cover brilliant film by time-sequence control module, and time-sequence control module also exports one group of control signal to the brilliant film of source electrode-cover and grid-cover brilliant film; The Power convert of input is show that the analog power voltage of needs, logic supply voltage, grid open voltage, gate off voltage, common port voltage for liquid crystal screen display by power module, is transported to the brilliant film of source electrode-cover and grid-cover brilliant film; Analog power to be divided into by the form of electric resistance partial pressure impact damper or gamma able to programme by gamma module to be organized gamma electric voltage more and is supplied to source electrode-cover brilliant film ten; The brilliant film of source electrode-cover and grid-cover brilliant film the signal handled well is separately flowed to thin film transistor liquid crystal display screen.
Beneficial effect of the present invention is: structure is simple, accurately controls the switch of each TFT circuit, coordinates backlight to demonstrate various picture.Avoid that plank is long causes processing difficulties, be unfavorable for the problems such as binding and maintenance.
