Abstract
The invention provides a liquid crystal panel data loading system. The system is arranged on a motherboard for connecting a liquid crystal panel; the liquid crystal panel is provided with a first pin header connector; the first pin header connector is provided with a first LVDS (Low Voltage Differential Signaling) data connecting pin and a first reserved connecting pin, and comprises a chip set, a second pin header connector, an LVDS screen line and a basic input and output system module and is used for connecting the liquid crystal panel and the chip set; the LVDS screen line is used for setting different defaults according to different types of liquid crystal panel signals; the basic input and output system module is connected with the chip set and data of various styles of liquid crystal panels of different types and the defaults of the LVDS screen line connected with the liquid crystal panels are previously stored in the chip set; the basic input and output system is used for detecting the defaults of the LVDS screen line of the connected liquid crystal panel through a GPIO (General Purpose Input/Output) data interface, the type of the liquid crystal panel is determined according to the defaults and the corresponding liquid crystal panel data is loaded.
Description
[technical field]
The present invention is a kind of liquid crystal panel data loading system.
[background technology]
The assembling of existing liquid crystal display normally first by liquid crystal panel data storing in EEPROM, then EEPROM is installed on mainboard, the shortcoming done like this: be the data that the liquid crystal panel of different vendor needs storage different, when mainboard is assembled, different FW assembly item number must be set up, imprinting different content is at EEPROM, in the system assembles stage, also need to set up different large rank item number collocation liquid crystal panel shipment again, be installed on again or by EEPROM liquid crystal panel behind, storage liquid crystal panel data, the shortcoming so done is: the liquid crystal panel of different vendor needs to store different data, and after stocking up, need to set up different FW assembly item number, imprinting different content is at EEPROM.Be welded on platelet, with adhesive tape, platelet be fixed on above panel.Above two kinds of methods all need to spend manpower and materials as can be seen here, for different panels imprinting different pieces of information, set up multiple BOM, be difficult to safeguard at factory's end, and can not use according to stock's elasticity, as worked as imprinting good category-A type panel data, but find that stock only has category-B profile plate, just needs EEPROM tip-off to get off, imprinting again, to burn-on again use, trouble very.
In view of this, the invention provides a kind of liquid crystal panel data loading system, it can load liquid crystal panel data automatically.
[summary of the invention]
Fundamental purpose of the present invention is to provide a kind of liquid crystal panel data loading system, and it can load liquid crystal panel data automatically
For reaching above-mentioned purpose, the invention provides a kind of liquid crystal panel data loading system, it is located on a mainboard for connecting fluid crystal panel, described liquid crystal panel has first row needle connector, described first row needle connector has a LVDS data cube computation pin and the first reserved connecting pin, it comprises: chipset, and it to be arranged on mainboard and to connect described central processing unit, and it has GPIO data-interface and LVDS data-interface; Second row needle connector, it has the 2nd LVDS data cube computation pin and the second reserved connecting pin, 2nd LVDS data cube computation pin of described second row needle connector connects the LVDS data-interface of described chipset, and the second reserved connecting pin of described second row needle connector connects the GPIO data-interface of described chipset; LVDS shields line, it reserves connecting pin in order to the LVDS data cube computation pin be electrically connected on described first row needle connector with the 2nd LVDS data cube computation pin on corresponding described second row needle connector and in order to connect second on the reserved connecting pin of first on described first row needle connector and corresponding described second row needle connector, for connecting described liquid crystal panel and described chipset, the liquid crystal panel that described LVDS shields line foundation different model arranges different default values; And BIOS module, it connects described chipset and is previously stored with many moneys different model liquid crystal panel data in described chipset and the LVDS that is connected with described liquid crystal panel shields the default value of line, and the LVDS of the liquid crystal panel that described BIOS module is connected by the GPIO data-interface detection of described chipset shields the default value of line and confirms the model of described liquid crystal panel according to default value and be loaded into corresponding liquid crystal panel data.
Compared with prior art, liquid crystal panel data load system of the present invention by the liquid crystal panel data that are previously stored with many moneys different model in chipset and the liquid crystal panel of corresponding different money arranges the LVDS with different default value shields line, the LVDS of the liquid crystal panel that described BIOS module is connected by the GPIO data-interface detection of described chipset shields the default value of line and confirms the model of described liquid crystal panel according to default value and load corresponding liquid crystal panel data, thus realizes the beneficial effect automatically loading liquid crystal panel data.
