- Correction Reference Voltage Circuit
- 7 -
Preliminary
γ
- correction reference voltage circuit consists of arrays of 13, 20, 21 series-connected resistor.
The reference voltage is fed to OP AMP for impedance conversion and is used as gray-scale voltage of
internal circuit.
5.5 Input Data Value and Output Voltage
Output voltage is determined by input data value and 5 reference voltage (V0 ~ V4).
And the relationship between input data value and output voltage is as follows.
(1) Reference voltage input for
γ
- Correction (V0 ~ V4)
This external voltage is reference voltage extracted from panel characteristics.
