With more and more LED screen widely used, ‘blurry screen’, ‘dirty
screen’ such ‘can’t calibrate’ problems has become a bottleneck
that directly reduce LED screen working life and increase practice
cost as well as restrict the development of LED industry. With 3
years unremitting effort, Dalian Dawning successfully developed
‘luminance and chrominance correction system’. Our own R&D
‘Online full-color LED screen luminance correction and color gamut
optimization method’ has obtained national invention patent which
can make *4bit pixel correction for LED chips luminance and
wavelength attenuation. This has filled a blank of internal market
and will completely improve current LED screen display effect as
well as promote our production export capability.
Dalian Dawning has cooperated with America Radiant Image and Japan
Cybernet in LED color correction and control field to create
domestic high-end market.
All our products comply with ROHS,CE,FCC certification. We’re
also‘***0 the 1st batch of Dalian software and service outsourcing
enterprise’.
advantage of dawning pixel correction system:
1.With QImaging PM***3F*1 CCD imaging colorimeter, the highest
metrical data accuracy in LED industry.Detail parameters refer to
below:
CCD type: QImaging,cooling type, single color, full frame
CCD
CCD size: *7.6×*8.4 mm
CCD resolution rate: ***8×***6
CCD dynamic range: *4bit=****4
Adopt RGB color matching with CIE color filter, chrominance
accuracy: ±0.**3, luminance accuracy: ±3%
Use ND filter, luminance measuring range: 0.**5～hundred of
thousands cd/m2
Measuring speed: luminance is 6sec, chrominance is about *0sec
2. Online full-color LED screen luminance correction and method of
color gamut optimization’ has obtained national invention
patent
Dawning’s ‘Online full-color LED screen luminance correction and
method of color gamut optimization’ obtained national invention
patent in February ***0. This patent is a core technology in
pixel chrominance and luminance correction control
3. D**2 control card with **-bit gray scale level model
algorithmic.
Current domestic mainstream LED control card displays gray scale
change from *-bit. Hence, accuracy of correction data exceeds the
maximum range that control card can save. After correction, can’t
achieve anticipitive display effect. Dawing’s D**2 control card
adopts **-bit gray scale model algorithmic, can completely output
after-correction compensation data to LED screen , making the
screen achieve the best display effect.
