Description
Technical field
The utility model relates to advertisement machine technical field, in particular to the liquid crystal display of a kind of self-service outdoor advertisement machine fills
It sets.
Background technique
Liquid crystal display device is the display equipment of planar ultra-thin, it is made of a certain number of colored or monochrome pixels, is put
It is placed in front of light source or reflecting surface.Liquid crystal display device power consumption is very low, therefore is favored by engineer, is suitable for using battery
Electronic equipment.Its cardinal principle is to generate point, line, surface cooperation back fluorescent tube with electric current stimulation liquid crystal molecule to be constituted picture.
The working principle of liquid crystal display device: liquid crystal is a kind of particular matter between a solid and a liquid, it is that one kind organises
Object is closed, is in a liquid state under normality, but its molecules align is but fairly regular as solid crystal, therefore is named liquid crystal, it
Another special nature is, if applying an electric field to liquid crystal, can change its molecules align, at this moment if cooperated to it
Polarized light piece, it just has the function of that light is prevented to pass through (when not applying electric field, light can be penetrated smoothly), if matched again
Close colored filter, change add to liquid crystal voltage size, can change a certain color light transmission capacity number, can also be figuratively
The voltage for changing liquid crystal both ends can change its light transmittance (but this must cooperate with polarizer in practice).However it is existing from
It helps the liquid crystal display device of formula outdoor advertisement machine there is some shortcomingss in use and carried out using hole is opened up
The effect of ventilation and heat, heat dissipation is poor.
