INTRODUCTION AND OVERVIEW

This is a product specification that specifies form, fit, and function of the 10.4” TFT LCD monitor and its

options. The LF1041 products are a family of high bright LCD monitors intended for use in a variety of

industrial and commercial applications. Some of these applications include Car TV, Kiosk, Control Panel,

Fish Finder, Marine, POI, Teketing, Aviation, Advertising, Gas Pumps, Signage... The LCD panel for

LF1041 has a particularly fast response time of 35ms and consequently very well suited for video applications.

The LF1041 is a 10.4” active matrix TFT LCD with a native resolution of 800X600 (SVGA). It has a typical

luminance of 1500 nits with a +12VDC input. The video interface is through a standard 15 pin analog input with

an integrated On-Screen Display (OSD).

OUTLINE

STRUCTURE AND PRINCIPLE

LF1041 module is composed of the driver LSIs for driving the TFT (Thin Film Transistor) array with an

amorphous silicon thin film transistor liquid crystal display (a-Si TFT LCD) panel structure and a backlight.

The a-Si TFT LCD panel structure is injected liquid crystal material into the narrow gap between a TFT array

glass substrate and a color filter glass substrate.

RGB (Red, Green, and Blue) data signals from a source system are modulated into a form suitable for active

matrix addressing by the onboard signal processor and sent to the driver LSIs which in turn address the

individual TFT cells.

Working as an electro-optical switch, each TFT cell regulates transmitted light from the backlight assembly

when worked by the data source. Color images are created by regulating the amount of transmitted light through

the array of red, green and blue dots.

Note 1: T= 25℃, IL = 6mA/Lamp (Total 6 lamps)

Note 2: Inverter should be designed with the characteristic of lamp. When you are designing

the inverter, the output voltage of the inverter should comply with the following

conditions.

(1) The area under the positive and negative cycles of the waveform of the lamp

current and lamp voltage should be area symmetric (the symmetric ratio should

be larger than 90%).

(2) There should not be any spikes in the waveform.

(3) The waveform should be sine wave as possible.

(4) Lamp current should not exceed the maximum value within the operating

Temperature (It is prohibited to over the maximum lamp current even if operated

in The non-guaranteed temperature). When lamp current over the maximum

value for a long time, it may cause fire. Therefore, it is recommend that the

inverter should have the current limited circuit.

Note 3: Lamp frequency may produce interference with horizontal synchronous frequency

and this may cause line flow on the display. Therefore lamp frequency shall be

detached from the horizontal synchronous frequency and its harmonics as far as

possible in order to avoid interference.

Note 4: Brightness (IL=6mA/Lamp) to be decrease to the 50% of the initial value.
