A flat panel display includes a backlight module, a liquid crystal display panel, and a complex diffuser plate. The liquid crystal display panel is disposed on the backlight module, and the complex diffuser plate including a first and a second diffusion layers is disposed between the backlight module and the liquid crystal display panel. Furthermore, the first diffusion layer is adjacent to the liquid crystal display panel and the second diffusion layer is adjacent to the first diffusion layer. The first and the second diffusion layers have different refractive indexes, transmittances and haze values, so that optical performance of the flat panel display is improved.

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.

A backlight module includes a back plate, replaceable light source sets, external electrode lamps, and a fastening device. Each replaceable light source set is disposed on the back plate and has an electrically conductive strip. The external electrode lamps are disposed on one of the replaceable light source sets and each has an external electrode electrically connected with the electrically conductive strip. The fastening device is used for fastening the replaceable light source sets and comprises an electrically conductive element electrically connected with the electrically conductive strips.

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.

A backlight module having a truss type structure comprises a plurality of truss type members, a reflector and at least a light source. The truss members and the light source positioned on the truss type structure. In a liquid crystal display (LCD) panel, the truss type structure disclosed in this invention is used as a main structure of such backlight module. Compared to those of the prior art, backlight modules that utilize the truss type structure of this invention have the advantages of reduced weight and better bending strength.

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.
