Targets And Tolerances For All Inputs - TCL L65P8M Series Service Manual

luminance or tristimulus values in video or still image systems.
You need adjust 4+3 gamma for different samples based on the color coordinates and target gamma offered by PQ
engineer. So each sample can get almost the same effect as PQ golden sample. The 4+3 gamma include 4 gamma
based on 4 different color temperature (cool, normal, warm1, warm2) and 3 gamma related to SDR to HDR (cool,
normal, warm).
For the automatic gamma correction, we can do as below, but please refer to "Gamma correction specification
(v1.00)"for detail.
▪Initialize the picture, turn off dynamic backlight, dynamic contrast,and set picture mode as computer desktop mode;
▪ Get the color coordinates (x, y, Y) and target gamma in the PDM of the target model;
▪ Open the factory menu of TV, Open the tools SIACP and main.vi on the PC, connect the equipment correctly
(CA310, serial port, PC, TV);
▪ Fill the color coordinates (x, y, Y) target gamma, error range and time-delay in the main.vi tool that made by AOE,
and save it;
▪ Put the probe on the middle of the panel, then run main.vi. The 4+3 gamma will be created and calibrated
automatically and saved in the TV.
As 4+3 gamma is a new and good way for PQ especially for HDR, we need adjust it in the factory now. And if we do
the 4+3 gamma, there is no need to adjust the white balance. But we need do the initial setup of white balance.
See Appendix⒂"How to do initial setup of white balance"
Note: The operation must enable factory "P" mode

Targets and Tolerances for all inputs


(According to company uniform LED color temperature standard of panel)
The measured and adjustable parameters should be mainly "x", "y" coordinates.
The White Balance alignment andAutomatic Gamma correction should be performed using a well calibrated and
contact less analyzer (ex: Minolta CA210 or CA310). The analyzer may not touch the screen surface, and
measurement must be performed in a dark environment keeping the probe(s) at 90+/-2° from the panel center.
The results should fulfill specification for each TV set offered by R&D and below tolerances:
