A buffer stage includes a first-half buffer stage and a second-half buffer stage, wherein an output of the first-half buffer stage is controllably fed back to a rail-to-rail differential amplifier, and an output of the second-half buffer stage is controllably fed back to the rail-to-rail differential amplifier. The switch network controls the connection between the outputs of the buffer stage and an output node of the half-power buffer amplifier in a manner such that a same pixel, with respect to different frames, of a display panel is driven by the same rail-to-rail differential amplifier. In one embodiment, the rail-to-rail differential amplifier and the buffer stage comprise half-power transistors operated within and powered by half of a full range spanning from power to ground.

摘要： An output buffer including a differential amplifier, a first and a second output stage, and a first and a second control stage is provided. The differential amplifier receives an input and a feedback signal and accordingly adjusts the level of the first and second control signals. The first control stage determines to provide a first current to an output terminal of the output buffer according to the level of the first and second control signals. The first control stage is biased under a high voltage and outputs one of the first control signal and the high voltage. The second control stage is biased under the low voltage and outputs one of the second control signal and the low voltage. The second output stage determines to provide a second current to the output terminal of the output buffer according to the signal generated by the first and second control stages.

摘要： A foldable toothbrush has a shell, a cover, a mounting sleeve, a handle and multiple bristles. The cover is mounted pivotally to the shell and selectively covers the top opening and part of the front opening of the shell. The mounting sleeve is mounted pivotally to the shell and is selectively pivoted into the shell. The handle is mounted in the mounting sleeve and is selectively rotatable and slidable in the mounting sleeve. The bristles are attached to the handle. With the handle being rotatable and slidable in the mounting sleeve, the whole length of the toothbrush is adjustable to selectively adapt for using or stowing. Furthermore, the cover keeps the handle and the bristles clean when stowing.
