LM185WH2

Liquid Crystal Display

Product Specification

1. General description

LM185WH2-TLE1 is a Color Active Matrix Liquid Crystal Display with a Light Emitting Diode(LED)
backlight system. 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(Low Voltage Differential Signaling) 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-TLE1
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.

whereas mosaic pattern(8 x 6) is displayed and fVis the frame frequency.

2. The current is specified at the maximum current pattern.

3. Permissive power ripple should be measured under VCC=5.0V, 25°C, fV (frame frequency)=75Hz

condition and At that time, we recommend the bandwidth configuration of oscilloscope
is to be under 20MHz.

4. The duration of rush current is about 5ms and rising time of power Input is 500us  20%.

LED driver design guide

: 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 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±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
