LM310UH1
Liquid Crystal Display
Product Specification
1. General Description
LM310UH1 is a Color Active Matrix Liquid Crystal Display with a Light Emitting Diode (GB-r 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 31 inch diagonally measured
active display area with 4K2K resolution (4096 horizontal by 2160 vertical 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 10-bit gray scale signal for each dot,
thus, presenting a palette of more than 1.07Billion colors. It has been designed to apply the 10-bit 8port
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.

Unit Notes
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 recommend that Dimming Control Signal (PWM Signal) is synchronized with Frame
Frequency for Wavy Noise Free.
1. 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 specified voltage is input LED string and Bar voltage at typical Current 100% duty current.
4. The specified power consumption is input LED bar power consumption at typical Current
100% duty current.
5. The life is determined as the time at which luminance of the LED is 50% compared to that of
initial value at the typical LED current on condition of continuous operating at 25 2¶C.
6. The power consumption shown above does not include loss of external driver.
The used LED bar current is the LED typical current.
The typical power consumption is calculated as
Bar = Vs(Typ.) x (I_green(Typ.)+I_blue(Typ)) x No. of strings.
P
The maximum power consumption is calculated as
Bar = Vs(Max.) x (I_green(Typ.)+I_blue(Typ)) x No. of strings
P
7. LED operating DC Forward Current must not exceed LED Max Ratings at 252 C
Green & Blue LED can be operated at 0~10mA current range, but LGD can not guarantee
the optical performance at this low current level.
8. Blue current Ratio is calculated with I
B(typ.)/IG(typ.) after 30min. aging time at 25 2 C.
It means the Blue current portion comparing with Green current at 100% duty typical current.
