Abstract: A pulse width modulator includes a discrete time oscillator, a data storage device, a data processing block, a counter, and a comparator. The discrete time oscillator generates a first address of bits used by the data processing block for reading first data from the data storage device. The data processing block generates second data from the first data and at least one bit of the first address bits. The comparator generates a pulse width modulation signal by comparing the second data and a digital count generated by the counter.

Abstract: A voltage transform circuit transforms a transferred voltage to a desired magnitude of voltage. The voltage transform circuit includes: a first power supply unit for providing a digital voltage (Vdd-1) of a first magnitude; a second power supply unit for providing an analog voltage (Vaa-2) of a second magnitude; and a voltage transform unit formed with a plurality of MOS transistors, wherein the MOS transistors operate to transfer the digital voltage (Vdd-1) from the first power supply unit, and output a digital voltage (Vdd-3) of a third magnitude corresponding to the analog voltage (Vaa-2) transferred from the second power supply unit. By using an analog voltage (Vaa-2) that is higher than the digital voltage (Vdd-1), it becomes possible to increase the magnitude of the output digital voltage (Vdd-3). By supplying this high digital voltage (Vdd-3) to a charge pump, the level of the charge pump is lowered.

Abstract: The present invention relates to a backlight unit with sag control patterns, comprising a light source formed in a side surface of a light guide plate; and a plurality of optical patterns formed on a lower surface of the light guide plate, sag of the plurality of optical patterns increasing as the optical patterns become more distant from the light source. By controlling sag of optical patterns formed in a light guide plate, efficiency of light emitted from a backlight unit can be improved and uniformity of the light can be maintained. Also, since sag of optical patterns can be controlled, by increasing the number of optical patterns (by improving fill factor), light efficiency and uniformity can be controlled easily. Also, compared with a conventional method for manufacturing white dot patterns, white dot patterns can be more efficiently manufactured in terms of development time and costs.
