Description
Technical field
The present invention relates to television set tconless screen module software controlling techniques field, more particularly to a kind of tconless screens
The management of multi-screen ginseng and the method for pre- point screen.
Background technology
With the progress of Display Technique, in order to further reduce the production cost of TV, there is tconless in the market
Display screen.Tconless display screens namely remove traditional liquid crystal display screen TCON modules by other chips or front end master chip
To realize this partial function, the production cost of display screen is thus reduced.The effect of TCON modules is the figure that master chip is sent
As data input signal (input signal includes RGB data signal, clock signal, the class signal of control signal three) passes through its processing
Afterwards, it is converted into driving the signal of liquid crystal display, then is routed directly to the driving process chip of liquid crystal display.
Just realize that this partial circuit can be fabricated separately by single chip in this partial function of TCON modules a few years ago
Into small plate module, a big plate of circuit can also be formed with front end TV master chip together fabric swatch.In recent years, each TV main core
Positive this partial function TCON modules of piece design producer is integrated into TV master chip, and so TV production cost can be with
Further reduce, and the exploitation of TCON softwares is safeguarded to be integrated into be managed collectively in whole set of television software and safeguarded.No matter
It is the driving data which kind of scheme is required for specific staff development tconless screens, in start, the drive of tconless screens
Dynamic data are loaded into TCON modules to drive a screen.Due to the driving side of the even different size tconless screens of different screen producers
Case is different, causes difference of the TCON modules to the type of drive of screen, will make it that the driving data of TCON modules is different.
For former scheme, the driving number of specific tconless screens will be integrated into the driver of module chip
According to.In electric module chip independent operating in start, the driving data that will load tconless screens carries out a bright screen, therefore should
The shortcomings that scheme is exactly that the driver of a module chip is only supported to drive a tconless screen.In production, if
Different types of tconless screens, it is necessary to which the module plate for supporting different tconless screens is entered in multiple module drivers, burning
In.Complexity just aobvious, error-prone so in management service, and module chip program and TV master chip program are that have difference
People's separate management safeguard.
For latter scheme, because production cost is low and the driving data of tconless screens can cover master chip
It is managed collectively and safeguards in program, therefore supports tconless screens scheme all to use which from now on.So if can
Different types of tconless screens are supported in solution in same edition owner's chip image program, then are all for production management
Very big progress.It is, the simultaneous of the tconless screens of solution different model is just needed for TV software developer
Appearance processing, that is, need to propose a kind of tconless multi-screens ginseng management method.Way at this stage is drawn in start boot
Just then loaded during helical pitch sort run according to the screen title in EEPROM into the subregion for preserving tconless screen driving datas
The driving number strong point screen of tconless screens.The limitation of this way is exactly that boot needs to support file system, and
Need to be addressed to the subregion for the driving data for preserving all tconless screens, if the boot of certain chip manufacturer
Technical scheme do not support file system if, this method just fails.Another way is exactly to be protected using raw partition mode
Deposit the driving data of tconless screens.This way is sky data when first powering on start, in raw partition, it is necessary in system
After middleware program operation, the driving data of the screen is write in raw partition again after confirming the model of current tconless screens, because
This this method can be black state when first powering on start, easily occur maloperation in process of production, and occurring
Unusual condition can not also be found in time.

According to support preserves the screen driving datas of set tconless screens more, and startup is all to call to correspond to from tcon subregions to system every time
The screen driving data of tconless screens；
B, when compiling complete machine upgrading software, the screen of the tcon subregions write-in acquiescence tconless screens in step A is driven
Data, the driving data of the acquiescence tconless screens are typical case's screen driving datas by all tconless screens producers used
Formed with the screen driving data of a certain specific model screen, typical case's screen driving data is same producer, various sizes of
The unified screen driving data of tconless screens, the screen driving data of the specific model screen are specifically shielded for the tconless screens
Driving data；
C, after the completion of complete upgrading when first powering on start, own in the tcon subregions in traversal step A
The screen title of tconless screen driving datas and matched with the presently used screen title preserved in E2PROM, with true
Set the tone with that group screen driving data；If the presently used screen name preserved in E2PROM is not matched in tcon subregions
Claim, then just matched with producer's name；
D, after System Middleware program behaves, can be gone according to the presently used screen title preserved in E2PROM
EMMC another subregion calls screen driving data used in current screen, and then the screen driving data, tcon is covered in erasing entirely
Subregion；So the screen driving data of tcon subregions is just simply current shields screen driving data used；
E, every time on when establishing machine by cable, after System Middleware program behaves, can all check the screen title in E2PROM
Whether the screen title in called screen driving data is consistent with driving, if inconsistent repeat step D.
The present invention compared with the prior art, has advantages below and beneficial effect：

Brief description of the drawings
Fig. 1 is the theory structure block diagram of the embodiment of the present invention.
Embodiment
The present invention is described in further detail with reference to embodiment：
Embodiment one
As shown in figure 1, a kind of tconless screens multi-screen ginseng management and the method for pre- point screen, specifically include following steps：
When A. to EMMC subregions in addition to other subregions, 1 tcon subregion is further added by, the subregion is used for storing tconless screens
Screen driving data, support to preserve the screen driving datas of more set tconless screens.It is all from tcon subregions that system starts every time
Call the screen driving data of corresponding tconless screens.
B. when compiling complete machine upgrading software, the screen of the tcon subregions write-in acquiescence tconless screens in step A is driven
Data.The screen driving data of acquiescence tconless screens is typical case's screen driving data by all tconless screens producers used
Formed with the screen driving data of a certain specific model screen.Producer typical case screen driving data is to refer to drive the producer to be produced
Various sizes of tconless screens.The screen driving data of specific model screen refers to that typical case's screen driving data of the producer can not be used
Driving, it is necessary to the tconless screens screen driving data of oneself.All include screen title content in all screen driving datas.Factory
The screen title of family typical case screen driving data is to shield the abbreviation of producer's name, typically takes the abbreviation of 3 characters；For specific screen driving number
According to screen title be exactly the screen title.
C. start is first powered on after the completion of complete upgrading, it is all in the tcon subregions in traversal step A
The screen title of tconless screen driving datas and matched with the presently used screen title preserved in E2PROM, with true
Set the tone with that group screen driving data.If the presently used screen name preserved in E2PROM is not matched in tcon subregions
Claim, then with regard to being matched with producer's name (preceding 3 characters of screen title).The meaning of the step is, when first powering on,
Driving parameter in tcon subregions is not necessarily the definite driving parameter of the tconless screens, is " fuzzy " driving parameter.With " the mould
Paste " driving parameter carries out a screen, in process of production it is seen that the running status of the process TV.
D. after System Middleware program behaves, can be gone according to the presently used screen title preserved in E2PROM
EMMC another subregion calls screen driving data used in current screen, and then the screen driving data, tcon is covered in erasing entirely
Subregion.So the screen driving data of tcon subregions is just simply current shields screen driving data used.By this step, tcon subregions
In driving screen ginseng be exactly current tconless screens tangent screen driving data really, not be it is " fuzzy " shield driving data.
When E. starting shooting every time, after System Middleware program behaves, screen title and drive in E2PROM can be all checked
Whether the screen title in dynamic called screen driving data is consistent, if inconsistent repeat D steps.
The present invention divides 2 subregions, is tcon subregions and hwcfg subregions respectively in EMMC memories.Tcon subregions are
Raw partition, file system is not supported, only preserve the screen driving data of tconless screens, support to preserve the screen of multiple tconless screens
Driving data.Hwcfg subregions are the subregions of tape file system, for preserving the one of all tconless screens that the project is supported
A little related datas, include the data such as screen driving data, image quality parameter of each screen.The present invention is making the burning mirror image of master chip
During program, the data preserved in tcon subregions are to give tacit consent to the screen driving data of tconless screens, the screen of acquiescence tconless screens
Driving data is driven by typical case's screen driving data of all tconless screens producers used and the screen of a certain specific model screen
Dynamic data composition.Purpose using acquiescence tconless screens driving parameter is exactly that pre- point shields, that is, the after mirror image burning
When establishing machine on once by cable, the driving parameter in tcon subregions may not have the definite driving parameter of the tconless screens, be " fuzzy "
Drive parameter.Carry out screen with " fuzzy " the driving parameter, although it is possible that picture color not to the problems such as, in life
It is the running status it can be seen that TV during production.The reason for quoting this method is exactly support the tconless screens accurate
Driving parameter is just can determine that after middleware program behaves., can basis after System Middleware program behaves
The presently used screen title preserved in E2PROM goes hwcfg subregions to call screen driving data used in current screen, then
The screen driving data, tcon subregions are covered in erasing entirely.So just simply current screen is used for the screen driving data of tcon subregions
Shield driving data.By this step, the driving screen ginseng in tcon subregions is exactly current tconless screens tangent screen driving data really,
No longer it is " fuzzy " screen driving data.
Embodiment two
As shown in figure 1, a kind of tconless screens multi-screen ginseng management and the method for pre- point screen, present case is using Hai Si's
Hi3751V551 chips have Youda (AUO) and BOE (BOE) etc. more as movement master chip, the tconless screens producer of collocation
Kind screen.Specifically include following steps：
A. when to EMMC subregions, 80MB sizes are divided to tcon subregions.
B. compile upgrade file when, toward tcon subregions write-in default screen driving data.The default screen driving data is
Typical case's screen driving data of AUO and BOE screens producer and the screen driving data group of a certain specific model screen are used by project
Into.All AUO screens used in the project can shield driving data with a set of typical case and drive, but the drive of each size screens of BOE
Dynamic data are different, it is impossible to share typical case's screen driving data driving, therefore the BOE screens for using are just with respective specific screen
Driving data.
C. when complete upgrading first powers on, institute in the tcon subregions in boot guiding start-up phases, traversal step A
There is the screen title of screen driving data and matched with the presently used screen title preserved in E2PROM, to determine to call
That group screen driving data.If being not matched to the presently used screen title preserved in E2PROM in tcon subregions, that
With regard to being matched with producer's name (preceding 3 characters of screen title).
D. after System Middleware program behaves, screen title used in current driving is read with being preserved in E2PROM
The title of currently used screen contrasted, if screen driving data used in consistent explanation driving is correct；If
It is inconsistent, opened from hwcfg subregions in tcon files to shield the file of name command, this document underedge
TCON.bin data files wipe the data replaced in tcon subregions completely.
E. after System Middleware program behaves, screen title and drive in E2PROM can all be checked after start every time
Whether the screen title in dynamic called driving data is consistent, if inconsistent repeat D steps.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
