[NOTE]
1. The gap thickness is heavily affected by LCD types, glass thickness, TSP structure
2. Point diameter is affected by TSP performance
3. Response time is related to the channel counts, Cm, charger noise, LCD noise.
Suggested value may be changed according to the system properties.
4. The power consumption is measured under optimal system condition.
According to each system condition, the value can be different.
5. To avoid the typo, the table shall always have the correct values.
