  • Patent number: 10725334
    Abstract: A display device is provided to have an emission spectrum. The emission spectrum is performed in a white image of highest grey level and includes a first sub emission spectrum ranging from 380 nm to 478 nm and a second sub emission spectrum ranging from 479 nm to 780 nm, and the first sub emission spectrum has a maximum peak wavelength greater than or equal to 453 nm. An integral value of the first sub emission spectrum multiplied by a blue light hazard weighting function from 380 nm to 478 nm is defined as a first integration, and an integral value of the second sub emission spectrum multiplied by an eye function from 479 nm to 780 nm is defined as a second integration. A ratio of the first integration to the second integration is in a range from 40% to 65%.

  • Patent number: 9557459
    Abstract: A display apparatus comprises a display panel. The display panel emits a green light having a green energy and a green point of the CIE 1931 xy chromaticity under the operation of the highest gray level of a green image, and emits a blue light having a blue energy and a blue point of the CIE 1931 xy chromaticity under the operation of the highest gray level of a blue image. The ratio of the green energy to the blue energy is between 0.7 and 1.2. In the CIE 1931 chromaticity diagram, the coordinates of the blue point are bounded by the equation: y=?168.72x2+50.312x?3.635 and the equation: y=?168.72x2+63.81x?5.9174, while y is between 0.04 and 0.08.

  • Patent number: 9285627
    Abstract: A display module having a light source includes a display unit. The display unit includes a first substrate, a second substrate opposite to the first substrate, a display medium and a green filter layer. The display medium is disposed between the first substrate and the second substrate. The green filter layer is disposed on the first substrate or the second substrate. When the wavelength of the light is between 380 nm and 780 nm, the spectrum of the light source passing through the green filter layer corresponds to a first energy. When the wavelength of the light is between interval of 660 and 780 nm, the spectrum of the light source passing through the green filter layer corresponds to a second energy. The ratio of the second energy to the first energy is less than 2%.
