Level signal read module, the current level signal V of the AD mouthfuls of pin for obtaining liquid crystal television mainboard；
Configuration information searching modul, it is current with what level signal read module was obtained for being found in module database is shielded
Level signal identical level signal Vi, and obtain the corresponding screen module letter of the current level signal according to the mapping relations
Breath Mi；
Module information collocation module, for the screen module information Mi using the acquisition of configuration information searching modul to LCD TV
Screen ginseng, image quality configured.
Based on said system, the method for the present invention, as shown in figure 1, including step：
First, prefabricated screen module database, wherein, screen module database include standard screen and Tconless screens with confidence
Breath, the configuration information includes the AD mouthfuls of pin level signal of screen module information Mi and screen module information Mi and liquid crystal television mainboard
The mapping relations Vi-Mi of Vi；
Then, the current level signal V of LCD TV AD mouthfuls of pin of movement mainboard is obtained, wherein, as shown in Fig. 2 liquid crystal
The current level signal of AD mouthfuls of pin of TV is in liquid crystal television mainboard paster by installing the pull-up resistor of different resistances
R1 and pull down resistor R2 come partial pressure generation, AD mouthfuls of pin current level value V=(resistance of R2/(resistance of the resistance+R2 of R1))
× supply voltage value；
Then, shield module database in find with the current level signal V identical level signal Vi, and according to
The mapping relations obtain the corresponding screen module information Mi of Vi, that is, obtain the corresponding screen module information of current level signal V
Mi；
Finally, the screen of LCD TV is joined using the screen module information Mi for obtaining, image quality is configured.
Embodiment
A kind of method that embodiment provides compatible LCD TV standard screen and Tconless screens, comprises the following steps that：
1st, prefabricated screen module database, prefabricated screen module database include standard screen and Tconless screens with confidence
Breath, the configuration information includes reflecting for screen module information and screen module information and AD mouthfuls of pin level signal of liquid crystal television mainboard
Penetrate relation.
2nd, the AD mouthfuls of level signal of pin of default liquid crystal television mainboard can as needed be set to AD mouthfuls of allowed band
AD mouthfuls of pin of interior arbitrary value, such as LCD TV is 3.3V, can be used with the level of " 2.2V " correspondence standard screen
" 3.3V " level correspondence Tconless screens, the corresponding relation in prefabricated screen race database is as shown in table 1：
Table 1 is screen module information and the AD mouthfuls of relation table of pin level signal
| Screen module information | AD mouthfuls of pin level signal |
| Standard screen | 2.2V |
| Tconless screens | 3.3V |
Above level value is merely illustrative of, actually used to choose other values.
3rd, after LCD TV electrifying startup, first read AD mouthfuls of pin of liquid crystal mainboard as level signal V, the level signal
V can be determined by installing the pull-up and pull down resistor of different resistances in liquid crystal television mainboard paster come partial pressure.For example descend Fig. 2 institutes
Show, pull-up R1 (1K Ω) is connected moves power supply 3.3V to, drop-down R2 (2K Ω) connects and pulls down to ground, then the AD mouthfuls of current level letter of pin
Number be 2.2V, according to the corresponding relation of upper table, it may be determined that be standard screen.
4th, found in group of screens database with level signal V identical level signal Vi, obtained according to the mapping relations
The corresponding screen module information Mi of Vi are obtained, for example, when standard screen module is defined as, with standard screen module information to LCD TV
Screen ginseng, image quality are configured.
In embodiment of above, liquid crystal television mainboard can be determined that for standard as the case may be in production
Screen or Tconless screens, then when mainboard is produced, from suitable divider resistance, make the level signal of default AD mouthfuls of pin
Corresponded to completely with screen module information, so, when LCD TV starts, by reading default AD mouthfuls current level signal
Value, you can it is determined that specifically shield module, so as to configure corresponding screen ginseng and image quality information.
The present invention can be greatlyd save with same system software version come compatibility standard screen and Tconless screens simultaneously
Development and maintenance cost.
