Why Gamma Correction
深圳新视纪--高清视频专家,
•The Transmittance of the LC Spectra ( for medium-
to-high gray scale )
–The transmittance of the liquid crystal cell depends on the
wavelength of the transmitted light and the input level of
the signal.
•Light Leakage of Dark State for LCD Panel ( for
lower gray scale )
–Light leakage comes from pixel design, polarizers, and the
de-polarization effect of color filter.
–Spectra of BLU, polarizers, and color filter would effect the
chromaticites
of dark state
>> The different color temperature in each gray level.

Summary
•
•
•
•
•
•
深圳新视纪--高清视频专家,
The R G gamma curves overlap together and the gamma
value of B curve increases.
Gamma value of “white”almost keep the same, after fine
tuning gamma look-up tables.
Panels with white tracking would render images more naturally,
especially the grays and the warm colors (including the flesh
tones) benefit from this correction.
For the nature images, the white tracking solution can render
the images content lively and colorful since the bluish issue is
removed
White balance technology for TV application LCD panels, or
TCO 03”standard ( grayscale linearity ) for OA LCD panels,
would be the essential characteristic for good image quality.
Total time for fine turning grayscale linearity is about 3 hours.
