1. OUTLINE
1.1 STRUCTURE AND PRINCIPLE
SVA190WX1-05TB˄K˅(L)(M) 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.

Note1: The backlight of this product is made up of 4-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).

Note4: In case “FO” is not the recommended value, beat noise may display on the screen, because of interference
between “FO” and “1/th”. Recommended value of “FO” is as following.

*1. When VDD is on, but the value is lower than 4.5V, a protection circuit may work, then the module may
not display.
*2 The signal line is not connected with the module, at the end of cable the terminal resistor of 100 should
be added.
Note1: Display signals (D0+/-, D1+/-, D2+/-, D3+/- and CK+/-) must be “0” voltage, exclude the VALID
period (See above sequence diagram). If these signals are higher than 0.3 V, the internal circuit is
damaged.
If some of display 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 display signals, they should cut
VDD.
Note2: When VDD is on, it should be set above 4.0V.
Note3: The backlight power supply voltage should be inputted within the valid period of display and function
signals, in order to avoid unstable data display.
4.4.2 Power supply voltage ripple
When the power supply is designed, the next form can give the reference. If the voltage ripple is over the value in
next form, the noise should be seen in display area.
