Technical field
The present invention relates to a kind of flat-panel screens, particularly a kind of flat-panel screens of double-sided display type.
Background technology
General display is as important computer output equipment, just progressively to higher technical development.Though the technology of cathode-ray tube display has been in the stable maturity stage, the display of giant-screen and new technology has striden into the main flow ranks with also being unwilling to be outshone.Along with the introducing of the various new technologies of display, also just can produce some negative effects inevitably, for example, volume increasing, power consumption increase etc.Because the restriction on this physical arrangement, the range of application of cathode-ray tube display has certain limitation.Thereby, just more and more higher for the expectation value of novel display device.Along with improving constantly with progressively ripe of LCD Technology, it has become the new focus of monitor market.
Compare with traditional cathode-ray tube display, LCD has many advantages, at first aspect weight and volume, LCD is no matter be on weight, volume and thickness, all come short and small frivolously than cathode-ray tube display, therefore on Portability and ease of use, LCD is all superior than the conventional cathode ray tube display.
The principle of LCD is to utilize the physical characteristics of liquid crystal.Conducting when energising makes liquid crystal arrangement become orderly, and light is passed through easily; During no power, arrange and then become chaotic, stop light to pass through.Utilize this principle to make LCD.The structure of LCD, with tft liquid crystal, key part and component comprises glass substrate, colored filter, polaroid, drive IC, liquid crystal material, alignment film, backlight module, ITO conductive film etc.
Figure 1 shows that the LCD of a traditional driven with active matrix mode, at first the light by
area source10 impinges upon on the Polarizer 12, light is after passing Polarizer 12, can being polarized, the light of polarization can pass layer of
liquid crystal molecule14, wherein the arrangement mode of
liquid crystal molecule14 thin film transistor (TFT)
array22 that can be formed on the glass substrate is controlled, therefore
liquid crystal molecule14 can change the polarizing angle of polarization light, the light intensity that different polarizing angles forms can be different, the light of varying strength is red via
colored filter16 again, blue, green three pixels, will demonstrate the pixel of various brightness and different colours, just can form various images and the figure that user's 20 naked eyes are seen via another Polarizer 18 each pixels more at last.
Aforesaid traditional liquid crystal structure, generally only can be at a specific show image, yet along with the usable range of liquid crystal panel day by day enlarges, single face shows can not satisfy the demand gradually, for example mobile phone is often emphasized so-called PIP now, except that main panel, on phone housing, add another piece panel again, though the panel that adds, user's convenience can be increased, but cost can be increased.
Summary of the invention
Described in view of the foregoing invention background, traditional panel can only be in specific one side display frame, therefore in the time need showing two kinds of different pictures simultaneously, then needs extra another piece panel of use, causes the increase of use cost.
Therefore, fundamental purpose of the present invention provides a kind of planar display driving method, according to the method, can allow a flat display panel demonstrate different pictures in both sides.
Another object of the present invention is providing a kind of planar display driving method, can allow the user who lays respectively at the two-d display panel both sides watch different display datas.
A further object of the present invention is providing a kind of planar display driving method, can use single panel to reach the use effect of dual platen.
A further object of the present invention according to this structure, can allow a flat display panel demonstrate different pictures in both sides in that a kind of plane display device structure is provided.
The invention provides a kind of plane display device structure and method of operating thereof, use an area source respectively in the both sides of liquid crystal panel, the user who makes way for the liquid crystal panel both sides all can see image, come from staggered lighting in the acceptable scope of people's naked eyes persistence of vision simultaneously by pleasing both parties, in handoff procedure, cooperate glass substrate upper film transistor array simultaneously, import different signal of video signal and come the picture of control panel, the user who makes way for the panel both sides sees different image datas.
Area source can use one group of cold cathode fluorescent lamp or light emitting diode as light source jointly, or uses two groups of different cold cathode fluorescent lamp or light emitting diode as light source respectively.And the liquid crystal structure that is suitable for can be the liquid crystal display device structure of transmission-type or semi-transmission-type.And selected liquid crystal molecule can be TN type (Twist Nematic), STN type (Super TN), MTN type (Mixed TN), RTN type (ReflectiveTN), RSTN type (Reflective Super TN) or VA type (Vertical Alignment).
