Revision History Version and Date description Preliminary Edition

1. General description LM240W U8-V551B is a Color Active Matrix Liquid Crystal Display with an integral Light Emitting Diode (LED) backlight system. The matrix employs a-Si Thin Film Transistor as the active element. It is a transmissive type display operating in the normally white mode. It has a 24 inch diagonally measured active display area with WUXGA resolution (1200 vertical by 1920 horizontal pixel array). Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arranged in vertical stripes. Gray scale or the brightness of the sub-pixel color is determined with a 8-bit...

DATA DISPLAY GROUP The following are maximum values which, if exceeded, may cause faulty operation or damage to the Table.Absolute maximum ratings Note : 1. Temperature and relative humidity range are shown in the figure below. Wet bulb temperature should be 39 °C Max, and no condensation of water. 2. Storage condition is guaranteed under packing condition 3. Storage condition is guaranteed under packing condition FIG. 2 Temperature and relative humidity

3. Electrical specifications 3.1 Electrical characteristics It requires two power inputs. One is employed to power the LCD electronics and to drive the TFT array and liquid crystal. The second input power for the LED Backlight is typically generated by an LED Driver. The LED Driver is an external unit to the LCDs. Table Electrical characteristics Parameter MODULE : Power Supply Input Voltage Permissive Power Input Ripple Power Consumption Inrush current Power Supply Input Current Note : 1. The specified current and power consumption are under the VLCD=12.0V, 25 ± 2° V=60Hz C,f whereas mosaic...

3.2 Backlight Specification The backlight consists of one LED rail. Backlight Lifetime *1) VL is specified as the sum of the white LED forward voltages. *2) LEDs are best powered using a constant current source. To avoid chromaticity shifts while dimming use pulse-width modulation (PWM) techniques. *3) Backlight lifetime is defined as the time when brightness becomes 50% of the initial value. *4) The lifetime of the backlight is dependent of the ambient temperature. The lifetime will decrease under temperatures above 80°C unless LED forward current is reduced accordingly. *5) LED forward current...

DATA DISPLAY GROUP The brightness of each primary color (red,green and blue) is based on the 8bit gray scale data input for the color ; the higher the binary input, the brighter the color. The table below provides a reference for color versus data input. Table. Color data reference

DATA DISPLAY GROUP Table. Power sequence 1. Please VLCD power on only after connecting interface cable to LCD. 2. Please avoid floating state of interface signal at invalid period. 3. When the interface signal is invalid, be sure to pull down the power supply for 4. Lamp power must be turn on after power supply for LCD an interface signal are valid.
