Abstract
The invention relates to a liquid crystal screen and method for setting screen parameter. The method comprises steps as follows: a, acquiring different configurations of the system hardware via the port of the system hardware, and determining the pre-set electricity voltage of each system hardware in accordance with resolution type of different systems; b, forming a screen parameter index table from the pre-set electricity voltage of different system hardwares and resolution type of different systems; c, acquiring hardware configuration of the screen parameter, reading the corresponding record in the screen parameter index table, if there is no record corresponding to the screen parameter index table, selecting a default screen parameter and if there is a record corresponding to the screen parameter index table, selecting the screen parameter record; d, in accordance with the screen parameter selected in step c, setting the parameter value corresponding to the hardware scaler to make the hardware scaler scale OSD in accordance with the different setting parameters. The method for setting screen parameter provided by the invention realizes multiple physical resolution rates by one target code set, reduces the software development difficulties and improves the production efficiency and the operation efficiency of the system.
Description
Technical field
The present invention relates to the method that LCD screen is provided with screen ginseng, be particularly suitable for but be not limited only to setting the liquid crystal television screen ginseng.
Background technology
At present when the liquid crystal TV set screen to different physical resolution shows; Realize that the identical OSD of style (On-Screen Display) shows; In general, make, and choose the screen parameter certificate of correspondence with the corresponding many cover OSD system of screen physical resolution; Produce many cover OSD and many cover object codes according to different physical resolution, realize the different screen of the corresponding multiple physical resolution of same software version.This mode makes that software development difficulty large period is long, and it is big to take the memory space of system, owing to need generate corresponding OSD and object code to different physical resolution, so the speed of service is also corresponding slower, and the overall maintenance difficulty of system is bigger.
Summary of the invention
The invention provides the method that a kind of LCD screen is provided with screen ginseng, use a cover object code to realize multiple physical resolution, to simplify the Development of Software difficulty, the operational efficiency with system of enhancing productivity.
LCD screen of the present invention is provided with the method for screen ginseng, comprises step:
A. obtain the difference configuration of system hardware through the port of system hardware, and confirm the preset voltage of system hardware separately according to the resolution type (as 1920 * 1080,1366 * 768,1024 * 768 etc.) of different system;
B. the preset voltage of said different system hardware and the resolution type of different system are formed screen ginseng concordance list one to one;
C. in the system initialization, obtain the hardware configuration of screen ginseng, read the corresponding record in the said screen ginseng concordance list,, then choose the screen ginseng of an acquiescence if do not meet the record of screen ginseng hardware configuration based on the configuration information that gets access to; If the record that meets the system hardware configuration is arranged, choose this screen ginseng;
D. systems soft ware is provided with hardware scaler (OSD scaler) corresponding parameters value according to the screen ginseng that step c chooses; Make the hardware scaler carry out corresponding convergent-divergent to OSD, realize the liquid crystal display screen of the compatible various different sizes of a cover object code according to the different parameters that is provided with.
Concrete, in screen ginseng concordance list, the screen of equal resolution and identical parameters is joined index assignment in an array, this design not only helps improving the search speed to data, also can reduce redundant data, improves operating factor of memory space.
Concrete, systems soft ware is through the level of reading system hardware port, the Hardware configuration described in the obtaining step c.
Difference configuration concrete, obtain system hardware among the step a through the different output levels of system hardware port.
Preferably, described system hardware port is GPIO (general input and output) port or AD (mould/number conversion) port.
LCD screen of the present invention is provided with the method for screen ginseng, uses a cover object code to realize multiple physical resolution, has simplified the Development of Software difficulty, has improved the operational efficiency of production efficiency and system.
Below in conjunction with embodiment, foregoing of the present invention is remake further detailed description by the accompanying drawing illustrated embodiment.But should this be interpreted as that the scope of the above-mentioned theme of the present invention only limits to following instance.Do not breaking away under the above-mentioned technological thought situation of the present invention, various replacements or change according to ordinary skill knowledge and customary means are made all should comprise within the scope of the invention.
Description of drawings
Fig. 1 is provided with the flow chart of the method for screen ginseng for LCD screen of the present invention.
Embodiment
LCD screen of the present invention as shown in Figure 1 is provided with the method for screen ginseng, comprises step:
A. the different output levels of GPIO port through system hardware or AD port obtain the difference configuration (when detecting the output level of AD port the AD port being carried out the A/D sampling of 6bit) of system hardware; And according to the resolution type of different system (as 1920 * 1080; 1366 * 768; 1024 * 768 etc.) confirm the preset voltage of system hardware separately, for example the preset voltage of 1920 * 1080 screens is 3V, and the preset voltage of 1366 * 768 screens is 0V; The preset voltage of 1024 * 768 screens is 1V, and reserves intermediate level to adapt to other different screen form;
B. the preset voltage of said different system hardware and the resolution type of different system are formed screen ginseng concordance list one to one; In screen ginseng concordance list, the screen of equal resolution and identical parameters is joined index assignment in an array; To improve search speed, reduce redundant data and improve operating factor of memory space data;
C. in the system initialization; Systems soft ware obtains the hardware configuration of screen ginseng through the level of reading system hardware GPIO port or AD port; Read the corresponding record in the said screen ginseng concordance list based on the configuration information that gets access to; If do not meet the record of screen ginseng hardware configuration, then choose the screen ginseng of an acquiescence; If the record that meets the system hardware configuration is arranged, choose this screen ginseng;
D. systems soft ware is provided with hardware scaler (OSD scaler) corresponding parameters value according to the screen ginseng that step c chooses; Make the hardware scaler carry out corresponding convergent-divergent to OSD according to the different parameters that is provided with; Produce the parameter of different screens and different OSD scalings thus, realize the liquid crystal display screen of the compatible various different sizes of a cover object code.
