| 20080239286 | Display panel, color filter and testing method thereof - A color filter with low color shift is defined by a light leakage spectrum in the dark state. The color filter is disposed between two polarizing plates so as to measure a first spectrum of dark state a(λ), wherein the polarizing directions of the polarizers are orthogonal to each other. A second spectrum of dark state b(λ) while the color filter is removed, and then a ratio spectrum of light leakage intensity I(λ)=(a(λ)/b(λ)) is determined. A maximum value P | 10-02-2008 |
| 20100110690 | Display and Method for Modifying Color Resists of Color Filter - A method for modifying color resists of color filter includes the steps of: providing a white light-emitting diode (WLED) emitting light having wavelength of λ | 05-06-2010 |
| 20100141871 | LIQUID CRYSTAL DISPLAY - A liquid crystal display is disclosed. The liquid crystal display includes a first backlight source, a second backlight source and a liquid crystal panel. The first backlight source provides magenta backlight and the second backlight source provides green backlight. The first and second backlight sources are alternatively driven periodically to provide backlight for illustrating images. The liquid crystal panel comprises a liquid crystal layer and a color filter. The liquid crystal molecules of the liquid crystal layer are controlled for adjusting the transmittance of the backlight provided by the first and second backlight sources. The color filter includes red pixel areas, transparent pixel areas and blue pixel areas for performing color filtering operations on the backlight penetrating through the liquid crystal layer. | 06-10-2010 |
| 20100182532 | Backlight Module and Liquid Crystal Display - A backlight module and a liquid crystal display are disclosed. In the backlight module having a reflector base, a phosphor layer is disposed on the reflector base, and a plurality of blue light emitting diode (LEDs) are disposed above the reflector base and the phosphor layer for emitting a first light beam. An optical film is disposed above the reflector base, the phosphor layer and the blue LEDs for allowing P-polarized light of the first light beam to pass therethrough and reflecting S-polarized light of the first light beam to the phosphor layer so as to excite the phosphor layer to generate a second light beam of which the wavelengths are different from those of the first light beam. After being reflected to the optical film by the reflector base, the second light beam transmits through the optical film, and mixes with the first light beam to generate white light. | 07-22-2010 |
| 20100188606 | HIGH COLOR SATURATION DISPLAY AND COLOR ADJUSTING METHOD THEREOF - A display device and a color adjusting method are provided. The display device includes a backlight source and color resists disposed above the backlight source for filtering the light from the backlight source. An intensity spectrum of the backlight source has several segments which includes a first segment having a peak value existing at a wavelength between 515 nm and 535 nm. The color resists have a peak transmittance, which is smaller than 75%, existing at a wavelength between 520 nm and 540 nm. In addition, the transmittance of the color resists is smaller than 0.05% at the wavelength of 730 nm. Since the wavelength ranges in the range mentioned above are correlated, the color resists are capable of adjusting the light from the backlight source to enhance the color saturation. | 07-29-2010 |

The display device includes a backlight source, a transmittance adjusting layer, and a display panel for receiving light from the backlight source. The display panel has a color filter disposed above the backlight source. A CIE standard illuminant C test result of the color filter falls into a predetermined scope. In a transmittance spectrum of the transmittance adjusting layer, an average transmittance at wavelength shorter than 495 nm is smaller than that at wavelength greater than 570 nm. | 07-29-2010 |
| 20100188612 | HIGH COLOR EXPRESSION DISPLAY DEVICE - A high color expression display device and a method for manufacturing the same are provided. The display device includes a backlight module and a display panel for receiving light from the backlight module. The display panel has a color filter layer which consists of a plurality of color resists above the backlight module. Lights from the backlight module pass through the color resists and out of the display panel to form an output light. A NTSC saturation of the output light may be greater or smaller than 60%, and a CIE standard illuminant C test result of the color resists may correspondingly fall into different predetermined scopes to prevent color shift and maintain brightness of the display device. | 07-29-2010 |
| 20110157871 | Display Device and Manufacturing Method Thereof - A display device and a manufacturing method thereof are provided. The display device includes a backlight module and a color resist layer. The backlight module generates an output light, wherein the output light has an emitting spectrum function BL(λ) corresponding to a wave length λ. The color resist layer has a blue resist unit, a green resist unit, a red resist unit, and a white resist unit, respectively formed on the backlight module, for filtering the output light generated by the backlight module. The color resist layer has an index function S(λ). The index function S(λ) has an interval maximum value in the wave length between 480 nm and 580 nm, wherein the interval maximum value is between 1.1 and 1.2. The manufacturing method includes providing a backlight module to generate an output light; selecting a blue resist unit, a green resist unit, a red resist unit, and a white resist unit in accordance with an index function S(λ); and combining the blue resist unit, the green resist unit, the red resist unit, and the white resist unit together to form a color resist layer on the backlight module for filtering the output light emitted by the backlight module. | 06-30-2011 |
