ral description

-TLC1 is a Color Active Matrix Liquid Crystal Display with a Light Emitting Diode

on

( 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 white mode.
It has a 18.5 inch diagonally measured active display area with HD resolution (768 vertical by
1366 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 colors with Advanced-FRC(Frame Rate Control). It has been designed to apply the
interface method that enables low power, high speed, low EMI. FPD Link or compatible must be
used as a LVDS chip. It is intended to support applications where thin thickness, wide viewing
angle, low power are critical factors and graphic displays are important. In combination with the
vertical arrangement of the sub-pixels, the LM185WH2-TLC1 characteristics provide an excellent
flat panel display for office automation products such as monitors.

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.

LED driver des

: 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. The specified current is input LED chip 100% duty current.

3. The specified voltage is input LED string voltage at typical 110mA 100% duty current.

4. The specified power consumption is input LED bar power consumption at typical 110mA 100%
duty current.

5. The life time 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 r 2¶C.

6. The LED bar power consumption shown above does not include loss of external driver.
The used LED string current is the LED typical current.
Typ Power Consumption is calculated with PBar = Vs(Typ.) x Is(Typ.) x Nstring
Max Power Consumption is calculated with PBar = Vs(Max.) x Is(Typ) x Nstring
