Liquid crystal technology, but not limited to this, and in other embodiments, control light device is using transverse electric field effect (In-Plane
Switching, IPS) liquid crystal technology.The common electrode 322 of control light device 320A is set on first substrate 321, and flatness layer 327 is set
It is placed in common electrode 322.Strip shaped electric poles 3252A is set on flatness layer 327, and insulating layer 324 is set on flatness layer 327
And cover each coordination electrode 325A.First substrate 321 is oppositely disposed with the second substrate 326, and liquid crystal layer 323 is located at control electricity
Between pole 325A and the second substrate 326.In the present embodiment, liquid crystal layer 323 includes multiple liquid crystal molecules LC.When control electricity
When pole 325A is powered, liquid crystal molecule LC can be distorted along being parallel on the direction of electric field.Whereby, control light device 320A can obtain with it is upper
The identical technical effect of embodiment is stated, this will not be repeated here.
In the present embodiment, each light emitting device group 120A and each coordination electrode that controller 400 can be such that contraposition is overlapped
325A is powered simultaneously.Under the above-described configuration, each coordination electrode 325A each light emitting device group 120A Chong Die with contraposition can be same
Shi Tong electricity is to form the subregion of high light transmittance.In this way, which subregion reflection display device can reach the function that part is shown
Energy.Whereby, light emitting device group 120A and coordination electrode 325A can obtain technical effect same as the previously described embodiments, herein not
It repeats.
In conclusion the subregion reflection display device of an embodiment of the utility model, since it can be by will be controllable
Reflecting mirror is set on display panel, thus can no power controllable mirrors so that subregion reflection display device reflection environment
Light, and there is high optical reflectance.In addition, by energization controllable mirrors to provide subregion reflection display device regulatable light
Reflectivity and high light transmittance, can be to avoid the ghost image of display image and reflected light, and promotes subregion reflection display device
Display quality.In addition, the light reflectivity of subregion reflection display device can be regulated and controled by energization controllable mirrors to reduce
The intensity of reflected light provides the function of the anti-glare of subregion reflection display device whereby.Further, since subregion reflection-type is shown
Device can be by controller so that each light emitting device group and each coordination electrode of contraposition overlapping are powered simultaneously, therefore can be
Control light device corresponds to the subregion that high light transmittance and light reflectivity are formed on the position of coordination electrode.In this way, subregion reflection-type
Display device can reach the function that part is shown, and avoid the ghost image of display image and reflected light, and then promote display quality.
In addition, since subregion reflection display device only need to be in the light emitting device group of subregion energized part that forms display image and right
The coordination electrode answered, therefore can further reduce the energy consumption of subregion reflection display device.
Certainly, the utility model can also have other various embodiments, without departing substantially from the spirit of the present invention and its essence
In the case of, those skilled in the art work as can make various corresponding changes and modifications, but these according to the utility model
Corresponding changes and modifications all should belong to the protection scope of the utility model the attached claims.
