Same function as the bottom prism Protects top prism

Same function as the bottom prism Increases luminance by 1.33 times than the bottom prism

Bottom Prism Collects light and increases luminance by 1.55 times than light guide plate

Protector

Collects and equalize light from the light guide plate

Lamp Light guide Receives light from lamp and equalize the light plate on the whole area (Flat/Wedge) Lamp Housing(Lamp Reflector)Pattern(Dot/Shibo/V-cut) Reflector


Transmits the light from guide plate again to maximize efficiency

Glow Discharge

Remark : Same principle of discharge : Electronic energy à Hg UV à Phosphor visible light, Only difference is the principle of initial electron generation Discharge Principle

• Thermion emission by filament heating à Hot Cathode

• Electron created by the collision energy of internal ion (Ar+, Ne+) and cathode

• Electron generated by the collision energy of internal ion (Ar+, Ne+) and cathode

• Hg consumption due to the combination of electrode material & Hg by the sputtering of electrode

• Determined by the rate of Ba, Ca loss, which is coated on electrode à Separated by high temperature or the collision of internal ion causing blackening of electrode à Great loss when starting (Consumption of 1 starting = consumption of lighting for about 1~2 hrs)

• Ion accelerated by high voltage & sputter of lamp glass by electron/ Phosphor damage • Hg consumption : Compound of glass/phosphor

Average : about 50,000 hrs

Short life span : about under 10,000 hrs

Long life span : over 70,000 hrs

Relatively low à Power loss by voltage drop of cathode (about over 100V)

High efficiency à Low power loss by relatively small voltage drop of cathode (about 10V)

Not much is known theoretically, but the result shows having high efficiency than CCFL à by small voltage drop of cathode than CCFL

• Narrow diameter by using rod type metal electrode • Φ1.6 is possible as of ’03

• Narrow diameter is impossible due to the characteristic of filament electrode • Φ6.5 is possible as of ’97

• Most favorable condition for narrow diameter by having no internal electrode

Life span

Efficiency

Others

• Discharge by the initial electron in lamp • Electron generated by the collision energy of internal ion (Ar+, Ne+) and cathode (electron emitting material: MgO, TiO2, etc.)

• Metal electrode emits free electron à Cold Cathode



Drive IC

GATE DRIVER IC(8EA) : Horizontal

Send signal from PCB to TFT-

T TYPE DRIVER IC (Tape Carrier Package)

DRIVER IC

Send signal from data line to TFT- Gate in series. Each IC controls 128 lines horizontally.

SOURCE DRIVER IC(5EA) : Vertical As the gate of TFT- is ON, pixel data is being sent from source to each pixel. Each IC controls 154 lines vertically.
