A method of displaying an image on a display panel having a plurality of pixels arranged as rows and columns includes calculating a row correction value corresponding to a pixel position of a received data based on an average luminance of pixels in a pixel row of a sample-grayscale image, calculating a column correction value corresponding to the pixel position of the received data based on an average luminance of pixels in a pixel column of the sample-grayscale image, generating correction data for the received data using a row correction value and a column correction value corresponding to a pixel position of the received data, and converting the correction data to a data voltage to provide a data line of the display panel with the data voltage.

A display panel apparatus includes a display panel and a timing controller, and a data driver. The display panel includes a first subpixel and a second subpixel. The timing controller is configured to receive a first subpixel data for the first subpixel and a second subpixel data for the second subpixel. When the second subpixel is determined to be defective, the timing controller generates a compensated grayscale of the second subpixel data. The data driver is configured to apply a precharge voltage to the second subpixel and a charging voltage to second subpixel through a data line, wherein the precharge voltage is based on a grayscale of the first subpixel data and the charging voltage is based on the compensated grayscale of the second subpixel data.

Method of driving display panel and display apparatus for performing the same

A power supply apparatus includes a storage battery, a power part and a solar battery part. The storage battery provides a charged voltage to an electronic device. The power part provides an external voltage to the electronic device and simultaneously charges the storage battery, upon determining that the external voltage is provided to the power supply apparatus. The solar battery part charges the storage battery using a voltage output by a solar battery upon determining that the external voltage is not provided to the power supply apparatus and the electronic device is not in use, and provides the voltage output by the solar battery and the charged voltage output by the storage battery to the electronic device, upon determining that the external voltage is not provided to the power supply apparatus and the electronic device is in use.

A backlight unit for a liquid crystal display which can achieve substantially uniform luminance over the entire display screen includes: a light-guide plate guiding incident light and having a diffusion pattern for emitting light upward, the diffusion pattern being formed on at least one of upper and lower surfaces of the light-guide plate; and a point light source assembly disposed on at least one side portion of the light-guide plate, the point light source assembly including a plurality of point-light-source elements and a support substrate, in which the point-light-source elements are disposed on the support substrate and supply the light to the light-guide plate. An edge portion of one surface of the light-guide plate, which is adjacent to the point light source assembly, includes a first region corresponding to the point-light-source elements and a second region corresponding to a position between the point-light-source elements. The diffusion pattern may be formed in such a manner that the second region has a higher density than the first region.
