  • Publication number: 20240105127
    Abstract: A display apparatus includes a display panel, a driving controller, and a data driver. The driving controller generates a data signal based on input image data. The data driver converts the data signal into a data voltage and outputs the data voltage to the display panel. The driving controller includes a deterioration compensator. The deterioration compensator generates an alpha value based on a ratio between a sensed current read from a portion of the display panel applied with a high power voltage or a portion of the display panel applied with a low power voltage and a predicted current calculated from the input image data and generates the data signal using the input image data, a stress value of a pixel, and the alpha value.

  • Patent number: 7659657
    Abstract: A flat fluorescent lamp which can be used with an LCD display includes a plurality of discharge channels. Pairs of electrodes are formed on both ends of the discharge channels. Each of the plurality of channels has an emitting section at the middle, and electrode sections on both ends thereof. A width of the electrode sections is the same as that of the emitting section. However, a height of the electrode sections is greater than a height of the emitting section, resulting in the electrode section having a cross-sectional area that is larger than that of the emitting section.
