Description
Technical field
The invention provides a kind of panel display module, refer to a kind of panel display module that only need use a polaroid especially.
Background technology
Flat display apparatus is present popular day by day a kind of display device, wherein LCD is more because have that external form is frivolous, power consumption is few and characteristic such as radiationless pollution, so be widely used on the portable type information products such as individual desktop PC screen and mobile computer, PDA(Personal Digital Assistant), mobile phone, even existing cathode-ray tube (CRT) (Cathode Ray Tube, CRT) trend of display and traditional tv of replacing gradually.
Generally speaking, (liquid crystal display module LCM) is the device of most critical in the LCD to LCD MODULE, and it comprises assemblies such as display panels and backlight module.Display panels ties up in the two sheet glass substrates layer of liquid crystal molecule is set, and first coating both alignment layers on each glass substrate usually is so that liquid crystal molecule is specific along one and direction that be parallel to glass surface is arranged.By electronic packages such as the transistor on glass substrate, electrodes, can electric field be provided and liquid crystal molecule is rotated with electric field level liquid crystal molecule, because the birefraction of liquid crystal molecule can change with the direction of liquid crystal molecule, just can make polarized light through liquid crystal molecule the time, produce the change of polarization direction.Therefore, the displaying principle of display panels promptly is in the upper and lower both sides of display panels one polaroid (polarizer) to be set respectively, and cooperates the light amount of the rotation of liquid crystal molecule with the control exiting surface, just can demonstrate picture.
Please refer to Fig. 1, Fig. 1 is the displaying principle synoptic diagram of a traditional display panels.The tradition display panels comprises two glass substrates 12, which is provided with electrode, and is provided with liquid crystal molecule 14 in the middle of the glass substrate 12.The both sides of glass substrate 12 then are provided with two mutually perpendicular first and second polaroids 16,18, therefore, do not apply at last figure under the situation of electric field, the natural light that light source produced is through first polaroid 16 time, can formation only have a linearly polarized light P, pass through glass substrate 12 and layer of liquid crystal molecule again.It should be noted that in the layer of liquid crystal molecule of suitable thickness liquid crystal molecule 14 can make the polarization direction of linearly polarized light P just change 90 degree and form linearly polarized light S, just can pass through second polaroid 18.On the other hand, when being applied voltage, liquid crystal molecule can change the direction (applying the situation of electric field as figure below) of liquid crystal molecule 14, for example make the direction of liquid crystal molecule 14 parallel with the electric field direct of travel, make linearly polarized light P through layer of liquid crystal molecule the time, can not change the polarization direction, just can't pass through second polaroid 18.From the above, convert light source to linearly polarized light by polaroid, and cooperate and to apply not to liquid crystal molecule that same electric field so could show grey-tone image so that linearly polarized light converts elliptical polarized light to, be that necessity of LCD designs so polaroid generally is set in the display panels both sides.
Yet the function of general polaroid is to make the linearly polarized light of a certain polarization direction can pass through polaroid, and will absorb perpendicular to the light of this polarization direction, that is can absorb 50 percent light, causes light utilization lower.Simultaneously, the polaroid that is arranged on both sides, display panels front and back can limit the size design of LCD MODULE, causes reducing effectively the thickness of LCD MODULE, is developmental another problem of present LCD MODULE.Therefore, how improving the LCD MODULE design, with the light utilization ratio of raising LCD MODULE, and effectively reduce its thickness, still is the problem that industry continues research.
