It is larger, it is incident to the polarization side for the reflected light that the polarised light of light reflection magnetizer 33 is formed under the action of light reflection magnetizer 33
Larger change can occur to, plane of polarization etc., few part is emitted through polaroid 6 in reflected light, and sub-pixel 3 can be regarded as not showing
Show；When it is not maximum to need the brightness of the display of sub-pixel 3, then current impulse controller 7 passes through first electrode 31 and the second electricity
Pole 32 makes light reflection magnetizer 33 be powered, at this point, light reflection magnetizer 33 is magnetized, and the magnetization degree of light reflection magnetizer 33
Will not be larger, it is incident to the inclined of the reflected light that the polarised light of light reflection magnetizer 33 is formed under the action of light reflection magnetizer 33
Shake direction, plane of polarization etc. can occur centainly to change, and polaroid 6 is partly penetrated in reflected light and is emitted, the brightness that sub-pixel 3 is shown is not
For maximum.
For reflective display panel, referring to Fig. 6, when realizing the display of reflective display panel, current impulse control
Device 7 is progressively scanned by grid line 4, and inputs corresponding signal to corresponding thin film transistor (TFT) 35 by data line 5, with to first
Electrode 31 inputs corresponding signal, meanwhile, corresponding signal is inputted to second electrode 32, keeps corresponding light reflection magnetizer 33 logical
Electricity, light reflection magnetizer 33 magnetize, light reflection magnetizer 33 to being incident to the polarization light action of light reflection magnetizer 33, with
The display of adjustment sub-pixel 3 and intensity when not showing and showing, realize the display of reflective display panel.
It please refers to Fig.1, Fig. 2 or Fig. 3, in embodiments of the present invention, the picture in order to improve reflective display panel is shown
Effect, the reflective display panel further include being located at black matrix 36 of the second substrate 2 towards the side of first substrate 1, black square
Battle array 36 is corresponding with grid line 4, data line 5, in this way, black matrix 36 can separate adjacent sub-pixel 3, prevents adjacent sub-pixel
3 there is a phenomenon where crosstalks, meanwhile, black matrix 36 can cover grid line 4, data line 5, when grid line 4, data line 5 using copper,
The made of metal such as aluminium, silver can prevent grid line 4, data line 5 there is a phenomenon where reflective when obtaining, therefore, can improve reflective display
The picture display effect of panel.
