  • Patent number: 9335023
    Abstract: The present application relates to a quantum dot lens and a manufacturing method thereof, wherein the quantum dot comprises a lens body in the form of a rotator, a light incident surface and a light exit surface are formed on the lens body, the centers of the light incident surface and the light exit surface are located in the center axis of the lens body; and quantum dot materials are filled inside the lens body. The quantum dot lens can be used with a single LED. Since the light excited from the quantum dot materials can directly meet the need of increasing the light emitting angle, the quantum dot lens has no need to be used with a second lens for light distribution; the quality of the backlight used in the backlight illumination can be improved; and the high gamut in the direct type backlight can be achieved.

  • Patent number: 9269287
    Abstract: A method and system for measuring the response time of an LCD are provided. The method comprises the following steps: step A: controlling the LCD to display a preset image; step B: obtaining the luminance of the LCD that is displaying the preset image, and outputting a luminance-time curve in which the luminance changes over the time; step C: correcting the luminance-time curve to obtain a corrected luminance-time curve, and calculating the response time of the LCD according to the corrected luminance-time curve. When implementing the present application, the measuring errors about the response time of the system for measuring the response time, which are resulted from using different actual luminance measuring devices, can be reduced or eliminated.
