Note (9) Color Grayscale Linearity
a. Test image : 100% full white pattern with a test pattern as below
b. Test pattern : Squares, 40mm by 40mm in size, filled with 255, 225, 195, 165, 135 and
105 grays steps should be arranged at the center of the screen.
c. Test method
-1st gray step : move a square of 255 gray level should be moved into the center of the
screen and measure luminance and u' and v' coordinates.
- Next gray step : Move a 225 gray square into the center and measure both
luminance and coordinates, too.
d. Test evaluation
'u' v' = (u' A - u' B) 2 + (v' A - v' B) 2
Where A, B : 2 gray levels found to have the largest color differences between them
i.e. get the largest u' and v' of each 6 pair of u' and v' and calculate the u'v'.

PRODUCT INFORMATION
(2) Lamp frequency which may produce interference with horizontal synchronous
frequency may cause line flow on the display. Therefore lamp frequency should be
detached from the horizontal synchronous frequency and its harmonics as far as
possible in order to avoid interference.
(3) Life time (Hr) is defined as the time when brightness of a lamp unit itself becomes
50% or less than its original value at the condition of Ta = 25 2 C and IL = 6.5mArms
(4) Designing a system inverter intended to have better display performance, power
efficiency and lamp reliability.
They would help increase the lamp lifetime and reduce leakage current.
a. The measurement should be done at typical lamp current.
b. The asymmetry rate of the inverter waveform should be less than 10%.
c. The distortion rate of the waveform should be 2 with 10% tolerance.
- Inverter output waveform had better be more similar to ideal sine wave.
