  • Patent number: 11719977
    Abstract: A light reflecting structure, a backlight module, and a display device are provided. The light reflecting structure is configured to reflect light emitted from plural light emitting units. The light reflecting structure includes a bottom portion and plural sidewall portions. The sidewall portions are erected on the bottom portion. The sidewall portions respectively and correspondingly surround the light-emitting units, and the light emitted from each of the light-emitting units can be directed to a light reflecting surface corresponding to each of the sidewall portions to be reflected outward. A distance P is defined between any two adjacent sidewall portions, and each of the sidewall portions has a height H1. The distance P and the height H1 satisfy a first inequality, and the first inequality is H1<P/2×tan ?. ? represents a complementary angle of a half light-intensity angle of each of the light-emitting units.

  • Publication number: 20070139327
    Abstract: A dot inversion driving apparatus for an analog thin film transistor liquid crystal display (TFT LCD) panel and the method thereof are disclosed. The driving apparatus includes a control circuit and a source driver IC. The control circuit rearranges the orders and polarities of the grayscale signals of the TFT LCD panel, divides the grayscale signals into two groups, and outputs one of the groups during one of two half periods of each frame. The source driver IC collects the grayscale signals output by the control circuit. During the first half period using one scan line of the first group as a unit, the source driver IC outputs the grayscale signals to the pixels of the first group; and during the second half period using one scan line of the second group as a unit, the source driver IC outputs the grayscale signals to the pixels of the second group.
