LCD Module Application Note

LS013B4DN04

INTRODUCTION

This Application Note provides additional design

assistance for Sharp’s LS013B4DN04 Memory LCD.

This module is a reflective, monolithic active-matrix liq-

uid crystal module utilizing Sharp’s CG-silicon thin-film

transistor process. It offers high performance and

power efficiency for compact display applications, with

a serial interface for simple integration.

Subjects covered will be:

• Mechanical Specifications, including dimension

drawings and connector specifications

• Absolute Maximum Ratings

• Optical Specifications, including view angles, reflec-

tivity, contrast, and risetime

• Electrical Characteristics, including interfacing and

signal timing information

• Design Notes

• Manufacturing Information, including handling and

storage

• Reliability Information

This Note is based on Sharp’s document number

LCP-1109027 and is designed to provide supplemen-

tary information for the Specifications for this part.

Always refer to the latest Specifications when

designing with these devices.

FEATURES

• Reflective monochrome panel

• Square aspect ratio (1:1)

• 1.35-inch screen with 96 × 96 resolution in a

9,216-pixel stripe array

• Serial interface for display control

• Screen data is arbitrarily renewable by line

• Built-in, 1-bit internal memory for data storage

• Super low power consumption TFT panel

• Attached FPC connector

• RoHS compliant
