Backlight module and liquid crystal displayer

The invention relates to the technical field of liquid crystal display, in particular to a backlight module and a liquid crystal displayer. The backlight module sequentially comprises a printed circuit board, a reflector plate, an LED light source and a diffusion plate from bottom to top. First protruding points are arranged on the light-in face, facing the LED light source, of the diffusion plate and around the projection, within the light-in face, of the LED light source. The first protruding points can conduct reflection diffusion on an illumination area, on the diffusion plate, of the LED light source, eliminate projection dark spaces and prevent light source gathering, so that the distribution of a light-emitting area on the diffusion plate is more uniform. Meanwhile, the LED light source can be independently controlled, local light control can be better achieved, and accordingly the display quality of a high-dynamic-comparison image is improved. The reflector plate can reflect leaking light again so that the light can irradiate the diffusion plate again, accordingly the utilization rate of the light source is increased, the light mixing distance is increased, and thinning design of the liquid crystal displayer is achieved easily.

Polymer dispersed liquid crystal film and preparation method thereof

The invention discloses a polymer dispersed liquid crystal film and preparation method thereof. The liquid crystal film comprises, by mass: 65-135 parts of a substrate material, 65-135 parts of a liquid crystal material, and 0.2-2.0 parts of glass microspheres. The substrate material is composed of, by mass: 10-20 parts of a macromolecular agent, 0.65-1.35 parts of a photo-initiator, and 55-115 parts of one selected from n-propyl methacrylate, n-octyl methacrylate, trifluoroethyl methacrylate, dodecyl methacrylate, and tert-butyl methacrylate. The macromolecular agent is composed of, by mass: 0.02-0.09 parts of azobisisobutyronitrile, 0.19-0.26 parts of a trisulfide ester chain transfer agent, and 10-20 parts of one selected from 4-methoxy styrene, 4-trifluoromethyl styrene, and 4-methyl styrene. With the method provided by the invention, problems of uncontrollable substrate molecular weight and structure of prior arts are solved, driving voltage of the polymer dispersed liquid crystal film is reduced, and on-state light transmittance is improved. Therefore, an ultraviolet radiation device is not needed, such that the method is energy-saving, environment-friendly, and safe.

Lighting apparatus of riding type vehicle

The invention provides a lighting apparatus of a riding type vehicle, wherein the light source type of the lighting apparatus is not restricted, the radiating light is not blocked by the key carried by the hand of a rider, and the key switch can be effectively lightened. A plane inclined portion (45) and a plane vertical portion (46) are formed on a leg guard plate (25) arranged opposite to a passenger, the inclined portion (45) is inclined foward wherein the portion above the vehicle is fronter than the portion below the vehicle, and the vertical portion (46) is vertically arranged from the inclined portion (45) to the portion above the vehicle. The portion lightened by the switch light (80) is positioned at the opening (45a) of the inclined portion (45) to be matched with a combined switch (50). The lighting surface of the switch light (80) is positioned at the opening (46a) of the vertical portion (46) to be matched with the switch light (80). When observed from the side of the vehicle body, the axis direction SJ of the lock core (56) of the combined switch (50) is crossed with the radiating direction PJ of the switch light (80) behind the vehicle body, and thereby the combined switch (50) is lightened from the front sideof the vehicle body.

A plastic granulation waste gas treatment device

A plastic granulation waste gas treatment device is disclosed, including a bottom plate, wherein a treatment box is fixed to the top outer wall of the bottom plate by bolts; a first exhaust fan is fixed to the top outer wall of the bottom plate by bolts; one end of an exhaust pipe of the first exhaust fan is inserted to the inner wall of one side of the treatment box; a semi-circular ring is fixedto the top inner wall of the treatment box by bolts, and is fixed to porous gas pipe through bots; a mounting frame is fixed to the inner wall of one side of the treatment box through bolts; and a metal screen is fixed in the mounting frame through bolts. Elastic rods swing under impact so as to drive spring strips to shake, and irradiation angles of ultraviolet illuminating lamps change along with shaking of the spring strips, thus increasing the range of irradiation of the ultraviolet illuminating lamps. Concave lenses increase the area of contact between waste gas and the device, the direction of movement of the gas is changed, and treatment time of the waste gas is prolonged again. Alternatively distributed positions make cracking more thorough.
