3.4cm (1.35-inch) Black-and-White LCD Panel

Sony Semiconductor 

LCX007BNB

[Description of operating mode]

The LCD panel has the following functions to easily apply to various uses, as well as various broadcasting

systems.

• Right/left inverse mode

• Up/down inverse mode

• 4:3 display mode with side-black display

These modes are controlled by three signals (RGT, DWN, and WID). The setting mode is shown below:

WID RGT

Mode

H H 16:9 right scan

H L 16:9 left scan

L H 4:3 right scan

L L 4:3 left scan

DWN

Mode

H Down scan

L Up scan

The direction of the right/left and/or up/down mean when Pin 1 marking is located at right side with the pin

block upside.

• The analog signal (SID) to display side-black shall be input by 1H inversion synchronized with the signal.

3. 3-dot Simultaneous Sampling

Horizontal driver samples SIG1, SIG2 and SIG3 signal simultaneously, which requires the phase matching

between SIG1, SIG2, and SIG3 signals to prevent horizontal resolution from deteriorating. Thus phase

matching between each signal is required using an external signal delaying circuit before applying video

signal to the LCD panel.

The block diagram of the delaying procedure using sample-and-hold method is as follows.

The LCX007 has the right/left inverse function. The following phase relationship diagram indicates the phase

setting for the right scan (RGT = High level). For the left scan (RGT = Low level), the phase setting shall be

inverted between SIG2 and SIG3 signals.
