Abstract: 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.

Abstract: A clamp structure of an external electrode lamp includes a first fixing device, a second fixing device, and a metal strip. The first fixing device has a first indentation and the second fixing device has a second indentation for clamping an electrode of the external electrode lamp. In addition, the metal strip is located between the first and second fixing devices to contact the electrode of the external electrode lamp for providing power. The electrode can be further equipped with a cushion for fixing the electrode onto the first and second fixing devices.

Abstract: The present invention provides a back light module, having an optical element, a light source and an outer supporting means. The optical element includes main body and protrusions which protrude from an edge of the main body. Contiguous protrusions with the main body form a positioning groove. The conjunction region between protrusion and main body is a fillet. The outer supporting means fixes the optical elements and the light source, which has at least one positioning component disposed on the edge of the back plate. The positioning component includes one inner wall near to edge of the main body, a side wall near to the protrusion and a transition wall connecting the side wall and the inner wall. A separate distance g between the fillet and the side wall so that the optical element can be prevented from cracking during the impact or shock test of the back light module.

Abstract: A display module is provided. The display module comprises: a display panel; a peripheral module; and a damper structure disposed between the display panel and the peripheral module. The damper structure comprises a fixed portion on the peripheral module; a supporting portion attached to a surface of the display panel; and a middle portion connected to and between the fixed portion and the supporting portion. Hence, the damper structure provides better support to prevent the light leakage from the gap between the display panel and the peripheral module, and provides better stress buffer during the impact test or other external forces so as to protect the liquid crystal panel from damage.
