Note 2. <1> A way of luminance control by a variable resistor

This way works when BRTHL (No. 5 pin) of CN3 is opened.

BRTL

Mating variable resistor

: 10 KΩ ± 5 %

Minimum luminance (50 %) : R = 0 Ω

BRTH Maximum luminance (100 %): R = 10 KΩ

R

<2> A way of luminance control by a voltage

This way works when BRTHL and BRTL are opend. The range of input

voltage between BRTH and GNDB is as follows.

Minimum luminance (50 %) : 2.5 V

Maximum luminance (100 %) : ≤ 1.2 V

<3> A way of luminace control by a current

This module can not use the luminance control by a current, because GNDB

is in contact with the frame.
