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.

LED driver design guide
1) The design of the LED driver must have specifications for the LED in LCD Assembly.
The performance of the LED in LCM, for example life time or brightness, is extremely influenced by
the characteristics of the LED driver.
So all the parameters of an LED driver should be carefully designed and output current should be
Constant current control.
Please control feedback current of each string individually to compensate the current variation
among the strings of LEDs.
When you design or order the LED driver, please make sure unwanted lighting caused by
the mismatch of the LED and the LED driver (no lighting, flicker, etc) never occurs.
When you confirm it, the LCD module should be operated in the same condition as installed in
your instrument.
2) LGD strongly recommend Analog Dimming method for Backlight Brightness control for Wavy Noise Free.
Otherwise, recommend that Dimming Control Signal (PWM Signal) should be synchronized with Frame
Frequency.
1. The specified values are for a single LED bar.
2. The specified current is defined as the input current for a single LED string with 100% duty cycle.
3. The LED life time is defined as the time when brightness of LED packages become 50% or less
than the initial value under the conditions at Ta = 25 r 2¶C and LED string current is typical value.
4. The power consumption shown above does not include loss of external driver.
The typical power consumption is calculated as P
The maximum power consumption is calculated as P
Bar =Vs(Typ.) x Is(Typ.) x No. of strings.
Bar =Vs(Max.) x Is(Typ.) x No. of strings.
5. LED operating conditions are must not exceed Max. ratings.
