Image quality management-control method of the brilliant TV based on colour temperature.
To achieve the goals above, the present invention adopts the following technical scheme: a kind of image quality pipe of LCD TV based on colour temperature
Prosecutor method, includes the following steps:
Step 1: choosing tv prototype, according to the debugging of the state of tv prototype for the Gamma in the composing software of mainboard production
And colour temperature data, one group of Gamma, Gain and Offset storage numerical value is determined, as standard storage data；
Step 2: also each pre- to changes in temperature both direction respectively in composing software in addition to one group of standard storage data that debugging obtains
One group of Gamma, Gain and Offset storage numerical value is stayed, one group of Gamma, Gain and the Offset reserved to cold direction stores numerical value
As cool colour storing data, one group of Gamma, Gain and Offset the storage numerical value reserved to warm direction store number as warm colour
According to；Step 3: before batch production, several LCD TV backlight mould group ontology colour temperature data before first testing determine that batch is raw
Produce the direction influenced using backlight lamp bar and O/C on backlight module ontology colour temperature and amplitude；
Step 4: backlight module ontology colour temperature is influenced using backlight lamp bar and O/C according to the batch production determined in step 3
Direction and amplitude, determine batch production mould group colour temperature data；
Step 5: the colour temperature data for producing mould group in batches are compared with the colour temperature data of debugging model machine, if batch production mould
The deviation of the colour temperature data of the colour temperature data and debugging model machine of group within the specified scope, is then directly produced；If batch production
The colour temperature data of mould group partially warmer than the colour temperature data for debugging model machine are more than colour temperature error limit, the then warm colour reserved composing software
Storing data switching is adjusted to default value；It is more than if the colour temperature data for producing mould group in batches are more colder than the colour temperature data for debugging model machine
The cool colour storing data switching that composing software is reserved then is adjusted to default value by colour temperature error limit.
Colour temperature error limit described in step 5 is 600~1200K.
The colour temperature error limit is 700K.
The LCD TV also has long-range remote control function based on the image quality management-control method of colour temperature, is carried out by remote controler
Remote control realizes the switching of storing data.
Beneficial effects of the present invention:
1, production efficiency is improved,
Colour temperature superscalar data caused by backlight lamp bar and O/C deviation can be quickly solved using image quality management-control method of the invention to ask
Topic, saves the time for debugging composing software again and mainboard upgrades the time 8H or more to do over again；
2, manpower working hour is saved,
The manpower working hour that mainboard upgrades again, former mode monthly average board upgrading are saved using image quality management-control method of the invention
50Kpcs, update time 3min/pcs/ people can save 2500 working hour of manpower/moon, equivalent member=150,000 expense 2500*60
Member/the moon；
3, Improving The Quality of Products,
Image quality colour temperature data can be efficiently controlled using image quality management-control method of the invention and more tend to central value in critical field
Position improves the CPK data of this index, improves image quality effect；
4, present invention also adds one keys of factory's remote controler fast to switch storing data function, when the colour temperature of batch production mould group has
Producing line automatic remote-control device code value can be directly set when relatively large deviation, achieve that different groups of colour temperature storages without additionally increasing manpower
The switching of data.
Detailed description of the invention
Fig. 1 is the flow chart of the image quality management-control method of LCD TV of the invention based on colour temperature.
Specific embodiment
The present invention is described in further detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, a kind of image quality management-control method of LCD TV based on colour temperature, includes the following steps:
Step 1: choosing tv prototype, according to the debugging of the state of tv prototype for the Gamma in the composing software of mainboard production
And colour temperature data, one group of Gamma, Gain and Offset storage numerical value is determined, as standard storage data Medium, in this implementation
In example, the standard storage data Medium is as follows:
Step 2: also each pre- to changes in temperature both direction respectively in composing software in addition to one group of standard storage data that debugging obtains
One group of Gamma, Gain and Offset storage numerical value is stayed, one group of Gamma, Gain and the Offset reserved to cold direction stores numerical value
As cool colour storing data Cool, one group of Gamma, Gain and Offset the storage numerical value reserved to warm direction are stored as warm colour
Data Warm；
In the present embodiment, the cool colour storing data Cool is as follows:
The warm colour storing data Warm is as follows:
Step 3: before batch production, first three LCD TV backlight mould group ontology colour temperature data is first tested, determines batch production
The direction that backlight module ontology colour temperature is influenced using backlight lamp bar and O/C and amplitude；
Step 4: backlight module ontology colour temperature is influenced using backlight lamp bar and O/C according to the batch production determined in step 3
Direction and amplitude, determine batch production mould group colour temperature data；
Step 5: the colour temperature data for producing mould group in batches are compared with the colour temperature data of debugging model machine, if batch production mould
Within the specified scope, then directly carry out production can satisfy colour temperature to the deviation of the colour temperature data of the colour temperature data and debugging model machine of group
Data demand；If the colour temperature data for producing mould group in batches are partially warmer more than 700K than the colour temperature data for debugging model machine, will compile soft
The reserved warm colour storing data Warm switching of part is adjusted to default value；If producing the colour temperature data of mould group in batches than debugging model machine
Colour temperature data are colder more than 700K, then the cool colour storing data Cool switching that composing software is reserved are adjusted to default value, realized
Meet the purpose of the tv product of bigger colour temperature deviation range with same software.
The LCD TV also has long-range remote control function based on the image quality management-control method of colour temperature, can by remote controler into
Row remote control realizes that a key fast switches the function of storing data；It can when the colour temperature for producing mould group in batches has relatively large deviation
Producing line automatic remote-control device code value is directly set, the switching of different groups of colour temperature storing datas is achieved that without additionally increasing manpower.
