LM290WW1
Liquid Crystal Display
Product Specification
1. General Description
LM290WW1 is a Color Active Matrix Liquid Crystal Display Light Emitting Diode ( White LED) backlight
system without LED driver. The matrix employs a-Si Thin Film Transistor as the active element.
It is a transmissive type display operating in the normally black mode. It has a 29-inch diagonally measured
active display area with Wide Full HD resolution (1080 vertical by 2560 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 gray scale signal for each dot, thus, presenting a
palette of more than 16,7M(True) colors. It has been designed to apply the 8Bit 4 port LVDS interface. It is
intended to support applications where thin thickness, wide viewing angle, low power are critical factors and
graphic displays are important. It is intended to support displays where high brightness, super wide viewing
angle, high color saturation, and high color are important.

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 other input power for the LED/Backlight is typically generated by a LED Driver. The
LED Driver. is an external unit to the LCDs.

Note :
1. Permissive power ripple should be measured under VLCD =12.0V, 25 C, fV(frame frequency)=MAX
condition and At that time, we recommend the bandwidth configuration of oscilloscope is to be under
20MHz. See the next page.
2. The specified current and power consumption are under the VLCD=12.0V, 25 2 C, fV=60Hz condition
whereas Typical Power Pattern [Mosaic] shown in the [ Figure 3 ] is displayed.
3. The current is specified at the maximum current pattern of [Figure 3].
4. Maximum Condition of Inrush current :
The duration of rush current is about 5ms and rising time of power Input is 500us r 20%.(min.).
