3. RELIABILITY TEST
2.6. LUMINANCE CONTROL
Note1: These data are the target values.
Test of the adaptable LCD module.
This test is in accordance with the Reliability Test of the adaptable LCD module. Refer to Reliability
Resistor control
Voltage control
Method
• Adjustment
point of the resistor is the minimum luminance. Also maximum point of the resistor is the
maximum luminance.
• Luminance ratio Note1
• Adjustment
between BRTI and BRTH terminal. This control method can carry out continuation
adjustment of luminance.
• Luminance ratio Note1
The variable resistor (R) for luminance control should be 10kΩ ±5%, 1/10W. Minimum
The resistor (R) must be connected between BRTH-BRTI terminals.
Voltage control method works, when BRTH terminal is 0V and VBI voltage is input
Luminance is the maximum when BRTI terminal is Open.
