is used to control an amount of the light from the backlight unit in consideration of brightness of the image, and thus power consumption in the backlight unit is reduced.
The dimming mode is classified into an analog dimming mode and a digital dimming mode. The digital dimming mode is performed by a pulse width modulation (PWM) method. The analog dimming mode controls an amount of electrical current applied to a light source while the light source of the backlight unit is in a full-on state, and thus brightness of the backlight unit is controlled. The digital dimming mode controls an ON/OFF of the light source to control the brightness of the backlight unit.ahead, but the inner straw component will disengage from the outer straw component if the inner straw component is carelessly pulled out in the opposite direction. Further, such prior art straw assemblies have no means for reliably maintaining the assembly in the extended state, namely, no means by which the straw assembly is prevented from readily contracting again and there is a danger that the straw assembly might contract and fall into the container, if the user carelessly pushes the assembly against the bottom of the container.
In view of the problems as set forth above, an extensible straw assembly has already been developed and is well-known, having means to prevent the inner straw component from readily disengaging from the outer straw component and to prevent the assembly, once
