Description
Technical field
The present invention relates to the screen mould group software controlling technique field television set tconless more particularly to a kind of tconless screens
The method of the management of multi-screen ginseng and pre- point screen.
Background technique
As there is tconless to further decrease the production cost of TV in the market in the progress of display technology
Display screen.Tconless display screen namely removes traditional liquid crystal display screen TCON mould group by other chips or front end master chip
It realizes this partial function, thus reduces the production cost of display screen.The effect of TCON mould group is the figure that master chip is sent
As data input signal (input signal includes rGB data signal, clock signal, control signal three classes signal) is handled by it
Afterwards, it is converted into that the signal of liquid crystal display can be driven, then is routed directly to the driving processing chip of liquid crystal display.
Just realize that this partial circuit can be fabricated separately by individual chip in this partial function of TCON mould group a few years ago
At small plate module, the 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 mould group of piece design producer is integrated into TV master chip, and so TV production cost can be with
It further decreases, and the exploitation maintenance of TCON software can also be integrated into whole set of television software and be managed collectively maintenance.No matter
It is the driving data which kind of scheme requires specific staff development tconless screen, in booting, the drive of tconless screen
Dynamic data, which are loaded into TCON module, drives a screen.Due to the driving side of the even different size tconless screens of different screen producers
Case is different, causes TCON mould group to the difference of the driving method of screen, the driving data of TCON mould group will be made different.
For former scheme, the driving number of specific tconless screen will be integrated into the driver of module chip
According to.When booting powers on module chip independent operating, the driving data that will load tconless screen carries out lighting screen, therefore should
The shortcomings that scheme is exactly that the driver of a module chip only supports one tconless screen of driving.In production, if there is
Different types of tconless screen, it is necessary to multiple mould group drivers, mould group plate of the burning into the different tconless screens of support
In.Complexity just aobvious, error-prone in this way in management service, and module chip program and TV master chip program are different
People's separate management maintenance.
For latter scheme, since production cost is low and the driving data of tconless screen may include master chip
It is managed collectively maintenance in program, therefore supports tconless screen scheme that can all use which from now on.It so if can
Different types of tconless screen is supported in solution in same edition owner's chip image program, then being all for production management
Very big progress.It is, just needing to solve the simultaneous of the tconless screen of different model for TV software developer
Appearance processing, that is, need to propose a kind of tconless multi-screen ginseng management method.Way at this stage is drawn in booting boot
Just according to the screen title in EEPROM when lead sort run, then loaded into the subregion for saving tconless screen driving data
The driving number strong point screen of tconless screen.The limitation of this way is exactly that boot needs support file system, and
Need to be addressed to the subregion for saving the driving data of all tconless screens, if the boot of certain chip manufacturer
Technical solution do not support file system if, this method just fails.Another way is exactly that raw partition mode is used to protect
Deposit the driving data of tconless screen.This way is sky data when first powering on booting, in raw partition, it is necessary in system
After middleware program operation, the driving data of the screen is written in raw partition again after confirming the model of current tconless screen, because
This this method can be black state when first powering on booting, be easy to appear maloperation in process of production, and occurring
Unusual condition can not also be found in time.

Detailed description of the invention
Fig. 1 is the theory structure block diagram of the embodiment of the present invention.
Specific embodiment
The present invention is described in further detail below with reference to embodiment:
Embodiment one
As shown in Figure 1, a kind of method of tconless screen multi-screen ginseng management and pre- point screen, specifically includes the following steps:
When A. to EMMC subregion in addition to other subregions, it is further added by 1 tcon subregion, which is used to store tconless screen
Screen driving data, support the screen driving datas for saving more set tconless screens.It is from tcon subregion that system starts all every time
Call the screen driving data of corresponding tconless screen.
B. when compiling complete machine upgrading software, the screen of the tcon subregion write-in default tconless screen in step A is driven
Data.The screen driving data of default tconless screen is the typical screen driving data by all tconless screen producers used
It is formed with the screen driving data of a certain specific model screen.Producer typical case screen driving data is to refer to that the producer is driven to be produced
Various sizes of tconless screen.The screen driving data of specific model screen, which refers to, cannot use the typical screen driving data of the producer
Driving, it is necessary to the screen driving data of the tconless screen oneself.It all include screen title content in all screen driving datas.Factory
The screen title of the typical screen driving data of family is to shield the abbreviation of producer's name, generally takes the abbreviation of 3 characters；For specific screen driving number
According to screen title be exactly the screen title.
C. booting is first powered on after the completion of complete upgrading, owned in the tcon subregion in traversal step A
It the screen title of tconless screen driving data and is matched with the currently used screen title saved in EEPROM, with true
It sets the tone with that group screen driving data.If being not matched to the currently used screen name saved in EEPROM in tcon subregion
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 subregion is not necessarily the definite driving parameter of the tconless screen, is " fuzzy " driving parameter.With " the mould
Paste " driving parameter carries out a screen, in process of production it is seen that the operating status of the process TV.
D. it after System Middleware program behaves, can be gone according to the currently used screen title saved in EEPROM
Another subregion of EMMC, which calls, shields driving data used in current screen, and the screen driving data is wiped entirely then and covers tcon
Subregion.The screen driving data of tcon subregion is just only current in this way shields screen driving data used.By this step, tcon subregion
In driving screen ginseng be exactly current tconless screen tangent screen driving data really, be not " fuzzy " screen driving data.
When being E. switched on every time, after System Middleware program behaves, screen title and the drive in EEPROM can be all checked
Whether the screen title in dynamic called screen driving data is consistent, if inconsistent repeat D step.
The present invention divides 2 subregions in EMMC memory, is tcon subregion and hwcfg subregion respectively.Tcon subregion is
Raw partition does not support file system, only saves the screen driving data of tconless screen, supports the screen for saving multiple tconless screens
Driving data.Hwcfg subregion is the subregion of tape file system, for saving the one of all tconless screens that the project is supported
A little related datas, the screen driving data including each screen, the data such as image quality parameter.Burning mirror image of the present invention in production master chip
When program, the data saved in tcon subregion are to default the screen driving data of tconless screen, the screen of default tconless screen
Driving data is driven by the typical screen driving data of all tconless screen producers used and the screen of a certain specific model screen
Dynamic data composition.Purpose using default tconless screen driving parameter is exactly that pre- point shields, that is, the after mirror image burning
When once powering on booting, it is " fuzzy " that the driving parameter in tcon subregion, which may not have the definite driving parameter of the tconless screen,
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 operating status it can be seen that TV during producing.The reason of quoting this method is exactly support the tconless screen accurate
Driving parameter is just can determine that after middleware program behaves.It, can basis after System Middleware program behaves
The currently used screen title saved in EEPROM goes hwcfg subregion to call screen driving data used in current screen, then
The screen driving data is wiped entirely and covers tcon subregion.Just only current screen is used for the screen driving data of tcon subregion in this way
Shield driving data.By this step, the driving screen ginseng in tcon subregion is exactly current tconless screen tangent screen driving data really,
It is no longer " fuzzy " screen driving data.
Embodiment two
As shown in Figure 1, a kind of method of tconless screen multi-screen ginseng management and pre- point screen, present case is using Hai Si's
Hi3751V551 chip has Youda (AUO) and BOE (BOE) etc. more as machine core master chip, the tconless screen producer of collocation
Kind screen.Specifically includes the following steps:
A. when to EMMC subregion, 80MB size is divided to tcon subregion.
B. compile upgrade file when, toward tcon subregion be written default screen driving data.The default screen driving data is
The typical screen driving data of AUO and BOE screen producer and the screen driving data group of a certain specific model screen are used by project
At.All AUO screens used in the project can use a set of typical screen driving data to drive, but the drive of each size screen of BOE
Dynamic data are different, cannot share typical screen driving data driving, therefore just use respective specific screen for the BOE screen used
Driving data.
C. when complete upgrading first powers on, start-up phase, institute in the tcon subregion in traversal step A are guided in boot
There is the screen title of screen driving data and matched with the currently used screen title saved in EEPROM, is called with determining
That group screen driving data.If being not matched to the currently used screen title saved in EEPROM in tcon subregion, that
With regard to being matched with producer's name (preceding 3 characters of screen title).
D. it after System Middleware program behaves, reads in screen title used in current driving and EEPROM and saves
The title of currently used screen compare, if screen driving data used in unanimously illustrating to drive is correct；If
It is inconsistent, it opens in tcon file in hwcfg subregion to shield the file of name command, this document underedge
TCON.bin data file wipes the data in replacement tcon subregion completely.
E. after System Middleware program behaves, screen title and the drive in EEPROM can all be checked after booting every time
Whether the screen title in dynamic called driving data is consistent, if inconsistent repeat D step.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
