Abstract: A data processing circuit according to an embodiment may include a reception circuit configured to receive image data including grayscale values associated with pixels disposed in a display panel. The data processing circuit may include a compensation circuit configured to calculate a final compensation value by multiplying a representative compensation value of each area and a global gain, and to produce converted image data. The data processing circuit may include a memory storing a representative compensation value associated with a grayscale value of each area of the display panel, and may include a transmission circuit configured to transmit the converted image data to a data driving circuit.

Abstract: A display apparatus having a mura compensation function includes a mura memory in which compensation data corresponding to coefficient values of a mura compensation equation is stored; and a mura compensation circuit configured to perform mura compensations on display data by using the mura compensation equation to which the compensation data has been applied, wherein the coefficient values are set so that the mura compensation equation has been fit to have a curve that satisfies known difference values of selected gray levels, a first estimation difference value of a first estimation gray level higher than the selected gray levels, and a second estimation difference value of a second estimation gray level lower than the selected gray levels, and wherein the compensation data comprises the coefficient values of the mura compensation equation in which all of the known difference values of the selected gray levels, the first estimation difference value, and the second estimation difference value have a differen

Abstract: Disclosed is a power source device having a standby power-cutoff function, which is to be used to charge a battery. The power source device comprises: a micro-USB connector (24) for connecting to the power source unit (20) of a smartphone when the battery of the smartphone or the like is to be charged; and a power generation unit (32) supplying DC charging power to the smartphone (20) from an AC input power source. The present invention includes: a control unit (33) having at least one microprocessor for controlling the overall operation and functioning of a power source device (30); a power supply/cutoff unit (34) supplying/cutoff the AC input power to the power generation unit (32) according to the control of the control unit (33); and a current-sensing unit (CT) connected so as to monitor the current from the power supply/cutoff unit (34), provide the control unit (33) with the current, and provide an indication of the charging state of the battery.

Abstract: The present invention discloses a charger (10) for blocking power when charging a battery (21). The charger includes a charging voltage generating unit (15) that generates a charging voltage for charging a battery.

Abstract: The present invention relates to a computer and a method for controlling same, in which power being supplied to a computer peripheral device is completely intercepted in a standby mode (power saving mode) or a monitor power-off mode during use of the computer, and power being supplied to the computer and to the computer peripheral device is completely intercepted when the power of the computer is turned ‘off’. Conventional computers have disadvantages that monitor screens are turned off but power is continuously supplied to monitors and computer peripheral devices that consume power in a standby mode (power saving mode) or a monitor power-off mode during use of the computer, and standby power of the computer is wasted when the power of the computer is turned ‘off’, and standby power of computer peripheral devices (monitor, printer, speaker, etc.) is continuously wasted. Such an unnecessary power waste may cause energy waste and generation of CO2, thus causing environmental contamination.
