Liquid Crystal Display
Product Specification
1. General Description
LM215WF3 is a Color Active Matrix Liquid Crystal Display with a 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 23 inch diagonally measured
a c t i v e d i s p l a y a r e a w i t h F H D r e s o l u t i o n ( 1 0 80 v e r t i c a l b y 1 9 2 0 h o r i z o n t a l p i x e l a r r a y)
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 colors with A-FRC (Advanced Frame Rate Control).
It has been designed to apply the 8Bit 2 port LVDS interface.
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 second 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 =5.0V, 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=5.0V, 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.
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.).
