Abstract
The invention discloses a method for improving gray scale of an LED display screen, and relates to the field of LED display. The method can ensure display color not to be distorted while improving gray scale of the LED display screen. The main points of the technical scheme are that determining gray processing data; processing the gray processing data through software; and storing processed gray processing data in display parameters, overlaying bit by bit, and displaying the data. The method is mainly used in display quality improvement of LED display screens.
Description
Technical field
The present invention relates to LED and show field, particularly relate to a kind of method improving LED display gray shade scale.
Background technology
Display device popular is in the market of all kinds, wherein, LED display has the incomparable technological merit of other display screens, there is power consumption few, brightness is high, operating voltage is low, power consumption is little, microminiaturized, easily mate with integrated circuit, drive simple, life-span is long, shock-resistant, steady performance, information can be shown, word, picture, animation, video etc., LED has become the epoch-making product of current Information Communication, be widely used in railway civil aviaton, stadiums, conference hall, highway, square, megastore, in securities market and multiple monitoring and scheduling.
Gray shade scale refers to from the darkest to the brightest in led display screen list luminance primary, the brightness progression that can distinguish, and the gray shade scale of led display screen is higher, and color is abundanter, and color is more gorgeous; Otherwise Show Color is single, change is simple.
In the market by the raising of software simulating LED display gray shade scale, put forward separately by each look, process, traditional way is that 8 bit data are extended to 12, give the low four of 12 bit data by low four of 8 bit data, 8 original bit data are given successively the high eight-bit of 12 bit data.Although add LED display gray shade scale like this, but the change of LED display color also very greatly, therefore causes LED display to show and there is color distortion.
Summary of the invention
A kind of method improving LED display gray shade scale provided by the invention, can ensure that display color is undistorted while raising LED display gray shade scale.
For achieving the above object, adopt following technical scheme:
The invention provides a kind of method improving LED display gray shade scale, comprising:
Determine gray proces data;
By software, described gray proces data are processed;
Gray proces data after process are stored in parameters of display, carry out step-by-step superposition, display.
In conjunction with first aspect, the present invention implements in scene in one, and the method for described raising LED display gray shade scale, is processed described gray proces data by software, comprising:
According to matlab software, generate .mif file, utilize correlationship formula to process data.
In conjunction with first aspect, the present invention implements in scene at another kind, and gray proces data after process are stored in parameters of display, carry out step-by-step superposition, display, comprise by the method for described raising LED display gray shade scale:
Through process, original 8 gray proces data are changed into rear 12 the gray proces data of process;
Rear 12 the gray proces data of described process carry out position separation;
After being separated, the bit-by-bit storage of gray proces data is in parameters of display;
After described separation, gray proces data carry out step-by-step superposition, display.
The method of raising LED display gray shade scale provided by the invention, by determining gray proces data;
By software, described gray proces data are processed; Gray proces data after process are stored in parameters of display, carry out step-by-step superposition, display, compared with prior art, can ensure that display color is undistorted while raising LED display gray shade scale.

21, gray proces data are determined.
22, according to matlab software, generate .mif file, utilize correlationship formula to process data.
Wherein, correlationship formula can be:
grammar=4095*[(pre_gray/255).^value];
grammar=round(grammar);
data=[pre_gray;grammar];
fid=fopen('rom.mif','w');
fprintf(fid,'WIDTH=8;\nDEPTH=256;\n\nADDRESS_RADIX=UN
S;\nDATA_RADIX=UNS;\n\nCONTENT BEGIN\n');
fprintf(fid,'%d:%d;\n',data);
fprintf(fid,'END;');
fclose(fid);
figure(1);
plot(pre_gray,grammar,'k-');
23, through process, original 8 gray proces data are changed into rear 12 the gray proces data of process.
24, rear 12 the gray proces data of described process carry out position separation.
25, after being separated, the bit-by-bit storage of gray proces data is in parameters of display.
26, after described separation, gray proces data carry out step-by-step superposition, display.
The method of raising LED display gray shade scale provided by the invention, by determining gray proces data;
By software, described gray proces data are processed; Gray proces data after process are stored in parameters of display, carry out step-by-step superposition, display, compared with prior art, can ensure that display color is undistorted while raising LED display gray shade scale.
