Abstract
The utility model discloses a kind of private Mura for display panels secondary development and repair framework, it is characterized in that comprising the display panels, time-sequence control module, switch, two EEPROM (Electrically Erasable Programmable Read Only Memo) that connect successively.Described time-sequence control module has a universal input/output interface, and interface connects a switch.Described switch comprises two kinds of settings, and one is set to not carry out Mura repair process; Another kind is set to carry out Mura repair process.Of the present utility modelly can to utilize on time-sequence control module reserved universal input/output interface and two EEPROM (Electrically Erasable Programmable Read Only Memo), the substandard products LCDs filtered out LCDs factory is carried out secondary development and is avoided the wasting of resources.
Description
Technical field
The utility model relates to image processing field, especially relates to a kind of private Mura for display panels secondary development and repairs framework.
Background technology
Present liquid crystal display product, main direct LED backlight technology or the side entering-type LED backlight source technology of adopting throws light on to liquid crystal panel, to realize the display of picture.When LED luminance is uneven, LED light just can not be thrown light on liquid crystal panel equably, and the Mura (Mura refers to the uneven moire phenomenon caused of display brightness) of brightness disproportionation appears in picture; On the other hand, on liquid crystal panel, different display unit is from distance different of LED, and also can cause the uneven of LED light on liquid crystal panel, Mura appears in picture, thus affects the display effect of LCD product, reduces the viewing quality of picture.
In traditional handicraft, display panels controls by time-sequence control module (Timer Control Register) adjustment result outputting to each display unit, makes display panels show correct view data.Time-sequence control module all can be connected with an EEPROM (Electrically Erasable Programmable Read Only Memo) (Electrically Erasable Programmable Read-Only Memory), for storing the contents such as related data, register, look-up table, the parameter preset that Mura repairs also is be stored in this EEPROM (Electrically Erasable Programmable Read Only Memo).
Consider that the time required for parameter preset that configuration Mura repairs is longer, many display panels factories do not carry out the parameter preset configuration of Mura reparation on a production line.Owing to lacking additional interface, time-sequence control module can only directly be connected with an EEPROM (Electrically Erasable Programmable Read Only Memo), without any extendability, so just causes once there is Mura, substandard products display panels directly can only be scrapped, cause the consequence of very large waste.
Summary of the invention
The utility model proposes a kind of private Mura for display panels secondary development and repair framework, be intended to solve due to hardware configuration existing defects, cause substandard products display panels directly to be scrapped, the problem of serious waste of resources.
Private Mura for display panels secondary development repairs a framework, it is characterized in that comprising the display panels, time-sequence control module, switch, two EEPROM (Electrically Erasable Programmable Read Only Memo) that connect successively; Described time-sequence control module has a universal input/output interface, and interface connects a switch.
Described switch comprises two kinds of settings, and one is set to not carry out Mura repair process; Another kind is set to carry out Mura repair process.
Concrete, display panels described in the utility model, time-sequence control module, universal input/output interface, EEPROM (Electrically Erasable Programmable Read Only Memo) all can adopt known schemes of the prior art, relevant above-mentioned known solution, those skilled in the art understands all, does not repeat them here.
Compared with prior art, effect of the present utility model is actively significantly, specifically: of the present utility modelly can to utilize on time-sequence control module reserved universal input/output interface and two EEPROM (Electrically Erasable Programmable Read Only Memo), the substandard products LCDs filtered out LCDs factory is carried out secondary development and is avoided the wasting of resources.
