摘要:
The invention is directed to a light module, which allows the individual lamp unit to be replaced with a new one and the luminance of the newly-replaced lamp unit can be automatically or manually adjusted to get a uniform luminance. Wherein, information of a first relation table of a lamp luminance versus a using time and a second relation table of the lamp luminance versus an operation current-power is used to determine the current power. In addition, a clocking unit is used to count a total using time for the light module. Then, a desired lamp luminance according to the first relation table can be determined, and then the current power is determined according to the second relation table.

A cut filter is used in a backlight module or a display device and positioned over the light source to filter off a part of the light comprising an overlap of at least two of the red light, the green light, and the blue light. By filtering off the overlapping part of light emitted from the light source to obtain a purer primary color light, the display device equipped with a conventional color filter can attain an improved color gamut.
