Into electric field, the liquid crystal molecule in the second liquid crystal layer 202 ' is driven, to control by the reflection light in the second reflecting layer 201 '
Amount of light, so as to realize the display of different GTGs；Certainly, the first display unit 101 can also be opposite with the second display unit 102
Set.
In addition, in order to ensure that the first color membrane substrates 203 do not have reflection light in the opening position of corresponding second display unit 102
Outgoing, and the second color membrane substrates 203 ' do not have reflection light outgoing, actual system in the opening position of corresponding first display unit 102
In work, light-absorption layer 204, the second color membrane substrates can be set in the position of corresponding second display unit 102 of the first color membrane substrates 203
The opening position of 203 ' corresponding first display units 102 sets light-absorption layer 204, and the light-absorption layer 204 can be mainly by black matrix material
Form.
Certainly, the devices such as oriented layer, polaroid are additionally provided with the reflective liquid crystal display panel, the present invention does not make to this
Repeat one by one.
Herein it should be noted that above-mentioned is only using reflective liquid crystal display panel as TN (Twist Nematic, distortion
Nematic) exemplified by illustrate, certainly, the reflective liquid crystal display panel can also be ADS (Advanced-Super

Show that the reflecting electrode 301 of sub-pix 100 in unit 102 is opposite with the position of transparency electrode 302.
Specifically, as shown in fig. 6, in the first display unit 101 reflecting electrode 301 relative to transparency electrode 302 close to base
OLED luminescent devices are top emission type in plate, namely the first display unit 101；The phase of transparency electrode 302 in second display unit 102
For reflecting electrode 301, OLED luminescent devices are bottom emitting type in substrate, namely the second display unit 102；Certainly, Fig. 5
Only it is that OLED luminescent devices are bottom emitting type in the illustration or the first display unit 101 illustrated, the second display is single
OLED luminescent devices are top emission type in member 102.
Certainly, it should here be understood that arriving, the substrate in above-mentioned OLED display panel is tft array substrate (TFT Array),
And the underlay substrate in the substrate should use transparent substrates substrate, such as clear glass etc..
This also provides a kind of double-side display device to the embodiment of the present invention, as shown in fig. 7, the double-side display device 001 includes
Drive circuit 02 and foregoing double face display panel 01；Wherein, drive circuit 02 includes：With the grid in double face display panel 01

A frame picture is required to 1/60s corresponding to one frame picture of data and the second display data, by frequency multiplier circuit 23 by first
After the output frequency of display data and the second display data increases to 2 times of incoming frequency (i.e. N=2), the first display data and
The output frequency of two display datas is 120Hz, then carries out the first display data after doubling frequency and the second display data
The display format shown after Data Integration by double face display panel is then maintained at 60Hz.
Certainly, if necessary to the display format of raising display picture, frequency multiplier circuit 23 can be increased to the first display data
With the increased multiple of output frequency of the second display data, such as N=4 can be set, then be 60Hz's for incoming frequency
For first display data and the second display data, it is by the display format shown after Data Integration by display panel
120Hz；The above is only signal for example, in practice properly according to the first display data and the second display data incoming frequency
And desired display format carries out selection setting, this is not limited by the present invention.
