The invention discloses a light source device of a projector, capable of enhancing brightness. The light source device is characterized by comprising a blue light generation part, a red light generation part, a multi-color light generation part and a light combining device, wherein the blue light generation part is constituted by a blue light LED (light-emitting diode) light source component and a fourth lens group arranged at the front end of the blue light LED light source component; the red light generation part is constituted by a red light LED light source component and a third lens group arranged at the front end of the red light LED light source component; the multi-color light generation part comprises a blue laser generation part, a fluorescence excitation part and a first dichroic mirror placed between the blue laser generation part and the fluorescence excitation part; and blue light, red light and multi-color light are gathered into a light-combined light beam on a same light shaft through a light combining effect of the light combining device to be irradiated on a light bar. The three-color light produced by the device has good color saturation, high luminous flux and high illuminance, so that the luminescence brightness of the projector is effectively upgraded and an excellent viewing effect is achieved. In addition, due to the simple structure, the convenience in production and the low cost, the device is suitable for extensive popularization.

A backlight module includes a light guide plate, a light source disposed at a side of the light guide plate, a diffuser sheet positioned over the light guide plate but not directly contacting the light guide plate, and a light mixing space positioned between the light guide plate and the diffuser sheet so that light emitted from the light guide plate efficiently mixes in the light mixing space before entering the diffuser sheet and emitted out of the backlight module.

A backlight module has a light guide plate having a transparent plate and a light-mixing structure. The light-mixing structure contains a light-convergence body and a light-dispersing body connected with each other to form an hourglass-shaped structure. With the light-mixing structure, the light guide plate can mix light beams of different colors to produce white light beams.

A transflective FPD device is provided. The transflective FPD device includes a liquid crystal layer and a transflective layer, the transflective layer including a plurality of reflective domains and a plurality of transmissive domains. The reflective domains are adapted for reflecting ambient lights, while the transmissive domains are configure for allowing backlight to pass therethrough. Each of the reflective domains has a plurality of reflective nano-particles distributed therein, thereon and / or thereunder for enhancing the reflecting ability thereof. The reflective domains are usually configured in a given pattern having either a long-distance or a short-distance order.

The invention relates to the technical field of display, and discloses an electrowetting display panel and a display device. The display panel comprises a first substrate and a second substrate which are oppositely arranged, wherein a first transparent electrode and an electric control dielectric layer of electrogenerated hydrophilic shading fluid or hydrophobic shading fluid are formed on the first substrate, a quantum dot solution is arranged between the shading fluid and the second substrate, when voltage is applied to the electric control dielectric layer through the first transparent electrode, shrinkage of the shading fluid is controlled, the quantum dot solution is exposed, light entering from the back side of the first substrate is irradiated to the quantum dot solution, quantum dots are stimulated to give out light automatically, colored display is achieved, high display brightness is achieved, the color is bright, color saturation is good, and the display effect is improved. Meanwhile, a sealed grid-shaped space is filled with the quantum dot solution and the shading fluid which are not compatible with each other, the transmission-type colored display device can be implemented through a single-layer electrowetting structure, the structure is simple, and the manufacturing technology is simplified.
