Product Specification

1. General description

LM190E0A-SLA1 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 black mode. It has a 19.0 inch diagonally measured active display area with SXGA
resolution (1024 vertical by 1280 horizontal pixel array) Each pixel is divided into Red, Green and Blue sub­pixels 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 sub­pixels, the LM190E0A-SLA1 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 an LED Driver. The LED driver is an external unit to the LCDs.

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

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

3. Permissive power ripple should be measured under VLCD=5.0V, maximum frame rate (fV) at 25°C.
Additionally, 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%.

Notes) The LED Bar consists of 30 LED packages, 2 strings (parallel) x 15 packages (serial)

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.

Notes :

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  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 PBar = Vs(Typ.) x Is(Typ.) x No. of strings.
The maximum power consumption is calculated as PBar = Vs(Max.) x Is(Typ.) x No. of strings.

5. LED operating conditions must not exceed Max. ratings.
