Abstract
A display device includes at least one light-emitting device and a color filter pattern. The light-emitting device is used to emit a white light having a white point chromaticity coordinates (Wx, Wy), where 0.228<Wx<0.278 and 0.186<Wy<0.315. The color filter pattern includes red, green and blue color filters. The peak wavelength of the red color filter is in a range of 725 nm to 780 nm, and its relative intensity is in a range of 0.95 to 1. The peak wavelength of the green color filter is 517±2 nm, and its relative intensity of the peak wavelength is in a range of 0.72 to 0.77. The peak wavelength of the blue color filter is 454±2 nm, and its relative intensity is in a range of 0.8 to 0.85.
Claims13
A display device, comprising:
- at least one light-emitting device, configured to provide a white light, wherein the white light has a white point chromaticity coordinate (Wx, Wy), wherein 0.228<Wx<0.278 and 0.186<Wy<0.315;
- and a color filter pattern, comprising:
- a red color filter, configured to convert the white light to a red light after the white light passes through the red color filter, wherein a peak wavelength of a transmission spectrum of the red color filter is substantially in a range of 725 nanometers (nm) to 780 nm, and a relative intensity of the peak wavelength of the transmission spectrum of the red color filter is substantially in a range of 0.95 to 1;
- a green color filter, configured to convert the white light to a green light after the white light passes through the green color filter, wherein a peak wavelength of a transmission spectrum of the green color filter is substantially 517±2 nm, and a relative intensity of the peak wavelength of the transmission spectrum of the green color filter is substantially in a range of 0.72 to 0.77;
- and
- a blue color filter, configured to convert the white light to a blue light after the white light passes through the blue color filter, wherein a peak wavelength of a transmission spectrum of the blue color filter is substantially 454±2 nm, and a relative intensity of the peak wavelength of the transmission spectrum of the blue color filter is substantially in a range of 0.8 to 0.85,
- wherein a display image provided by the display device has a white point chromaticity coordinate (Wx′, Wy′), where 0.221≦Wx′≦0.287 and 0.179≦Wy′≦0.352.
