1 Overview The Displaytech DT018BTFT & DT018BTFT-SHB are 1.8” color LCD modules, each composed of an active-matrix TFT panel, TFT driver, FPC cable with SPI interface, and adjustable LED backlight. The display area has a RGB pixel resolution of 128 x 160 pixels. The DT018BTFT-SHB, with twice the number of backlight LEDs, is available as a “super high-bright” alternative to the DT018BTFT. • Video systems • Mobile devices • Wearable devices • Module Dimensions a-Si, Transmissive, Normally white • Active Area • Pixel Pitch • Viewing Direction • Backlight Type Flexible Printed Circuit Liquid Crystal...

cP Displaytech3 Specifications3.1 Absolute Maximum Ratings Operation outside of the maximum ratings listed below may result in permanent damage to the LCD.

Figure 2: DT018BTFT-SHB Backlight 2x2 = 4 LEDs, lF = 40 mA Backlight Power Consumption: 140mW LED lifetime is defined as the amount of time it takes for brightness to decrease to 50% of its original value at TA=25°C and IF=40mA. LED lifetime may decrease if operating current, IF, is higher than 40mA.

Chromaticity = Area of △RGB / Area of △NTSC * Color coordinates measured at center point of LCD Figure 7: Luminance Uniformity Luminance is defined as the brightness of all white pixels at the center of the display area at optimum contrast. Uniformity is determined by measuring Luminance at 9 points and calculating LuminanceMIN / LuminanceMAX Contrast Ratio = Surface LuminanceWhitePixels Surface LuminanceBlackPixels

cP Displaytech 7 Precautions for Use of LCD Modules Liquid crystal in LCD is poisonous. Do not put in mouth. If liquid crystal comes in contact with skin or clothes, wash off immediately using soap and water. A. LCD panel is made of plate glass. Do not subject panel to mechanical shock or excessive force on its surface. B. In order to ensure reliability, do not hold product by flexible printed circuit (FPC) cable. C. Provide space so that panel does not come into contact with other components. D. Transparent electrodes may be disconnected if panel is used in an environment where dew condensation...
