When reaching preset condition, the reflecting part for controlling the first display area position for being disposed in proximity to display screen switches to reflection
State.
12. method as claimed in claim 11, which is characterized in that the degradation detector includes temperature sensor, for examining
The temperature of the illuminated display element positioned at the first display area in display screen is surveyed, whether is the aging conditions for judging to detect
Reaching a preset condition includes:
Judge whether the temperature for the illuminated display element that degradation detector detects reaches predetermined value；And
When the temperature of illuminated display element reaches predetermined value, it is determined that the aging conditions detected reach the preset condition.
13. method as claimed in claim 11, which is characterized in that the degradation detector is sensed including at least two brightness
Device is located at the first display area and the second display area of display screen, for sensing the first viewing area of display screen respectively
The brightness of the illuminated display element in domain and the second display area, it is described to judge whether the aging conditions detected reach one and preset
Condition includes:
Compare the illuminated display element of the first display area and the second display area that degradation detector detects brightness it
Whether difference reaches predetermined difference value；And
When the difference of the brightness of the illuminated display element of the first display area and the second display area reaches predetermined difference value, determine
The aging conditions detected reach the preset condition.
14. method as claimed in claim 11, which is characterized in that the degradation detector includes timer, in electronics
Timing is carried out after the bright screen of the display screen of device and obtains the accumulative timing time of bright screen, it is described to judge that the aging conditions detected are
The no preset condition that reaches includes:
Compare whether the accumulative timing time reaches predetermined value；And
When the accumulative timing time reaches predetermined value, the aging conditions confirmly detected reach the preset condition.
15. method as claimed in claim 11, which is characterized in that the reflecting part includes the reflection with two-layer film configuration
Film, the reflectance coating include the first reflectance coating and the second reflectance coating to fit together, and first reflectance coating is transparent membrane,
Second reflectance coating is transparent when being no power, and the film that opaque material is constituted after energization, the first reflectance coating is located at close
The side of display unit, the reflecting part for controlling the first display area position for being disposed in proximity to display screen switch to reflective condition
Include:
Control to the second reflectance coating be powered so that the second reflectance coating it is opaque and with the first reflectance coating constitute can reflection light knot
Structure.
