1. OUTLINE
1.1 STRUCTURE AND PRINCIPLE
SVA185WX1-02TB module is composed of the amorphous silicon thin film transistor liquid crystal display
(a-Si TFT LCD) panel structure with driver LSIs for driving the TFT (Thin Film Transistor) array and a backlight.
The a-Si TFT LCD panel structure is injected liquid crystal material into a narrow gap between the TFT array
glass substrate and a color-filter glass substrate.
Color (Red, Green, Blue) data signals from a host system (e.g. PC, signal generator, etc.) are modulated into
best form for active matrix system by a signal processing board, and sent to the driver LSIs which drive the
individual TFT arrays.
The TFT array as an electro-optical switch regulates the amount of transmitted light from the backlight
assembly, when it is controlled by data signals. Color images are created by regulating the amount of transmitted
light through the TFT array of red, green and blue dots.
1.2 APPLICATIONS
• For Monitor / TV application
1.3 FEATURES
• a-Si TFT active matrix
• LVDS interface
• R.G.B input 8bit, 16.77 millions colors (6bit+Hi-FRC)

• High contrast ratio: 1000:1
• High response time (Ton+Toff=5 ms˅
• High gamut: (against NTSC 72%typ.)

Note1: The backlight of this product is made up of 2-piece lamp. The specification above is only for each lamp.
Note2: The voltage timing cycle of each lamp should be set as the same phase. [Vs] and [VBLH] is the voltage
between the high port and low port, the value is the characteristic of lamp. The starting voltage of inverter
should be higher than the value. The possibility of not lighting exists by the lower voltage, so the suitable
voltage should considered by the test.

Note3: The asymmetric ratio of working waveform for lamps (Lamp voltage peak ratio, Lamp current peak ratio
and waveform area ratio) should be less than 5% (See the following figure). If the waveform is asymmetric,
DC (Direct current) element applies into the lamp. In this case, a lamp lifetime may be shortened, because a
distribution of a lamp enclosure substance inclines toward one side between low voltage terminal (Cold
terminal) and high voltage terminal (Hot terminal).

*2 :The signal line is not connected with the module, at the end of cable the terminal resistor of 100 should
be added.
Note1: In terms of voltage variation (voltage drop) while VCC rising edge is below 4.5 V, a protection circuit
may work, and then this product may not work.
Note2: If some of interface signals of this product are cut while this product is working, even if the signal input
to it once again, it might not work normally. If customer stops the interface signals, they should cut
VCC.
Note3: The backlight power supply voltage should be inputted within the valid period of interface signals, in
order to avoid unstable data display.
4.4.2 Power supply voltage ripple
This product works, even if the ripple voltage levels are beyond the permissible values as the following table,
but there might be noise on the display image.
