As shown in FIG. 3A, in the notebook computer mode, neither the flexible display panel 140 nor the third carrying mechanism 130 slides upward, and the first light sensing units SA1, SB1 do not correspond to the first light-transmitting areas PA1, PB1. Therefore, the first photosensitive measurements LA1 and LB1 are located at the low level "L". The second light-sensing units SA2 and SB2 do not correspond to the second light-transmitting areas PA2 and PB2 , so the second light-sensing measurements LA2 and LB2 are at the low level “L”. The third light-sensing units SA3 and SB3 correspond to the third light-transmitting regions PA3 and PB3 , so the third light-sensing measurements LA3 and LB3 are at the high level “H”.

As shown in FIG. 3C, in the large-screen mode, both the flexible display panel 140 and the third carrying mechanism 130 slide upwards, the flexible display panel 140 slides to the top, and the first light sensing units SA1 and SB1 correspond to the first transparent The light zones PA1 and PB1, therefore, the first light sensing measurements LA1 and LB1 are located at the high level "H". The second light-sensing units SA2, SB2 correspond to the second light-transmitting areas PA2, PB2, so the second light-sensing measurements LA2, LB2 are at the high level "H". The third light-sensing units SA3 and SB3 do not correspond to the third light-transmitting areas PA3 and PB3 , so the third light-sensing measurements LA3 and LB3 are at the low level “L”.

As shown in Figure 3D, in the shared screen mode, both the flexible display panel 140 and the third carrying mechanism 130 slide upwards, the flexible display panel 140 slides to the top, and the first light sensing units SA1 and SB1 correspond to the first transparent The light zones PA1 and PB1, therefore, the first light sensing measurements LA1 and LB1 are located at the high level “Ha”. The second light-sensing units SA2, SB2 correspond to the second light-transmitting areas PA2, PB2, so the second light-sensing measurements LA2, LB2 are at the high level "Hb". However, due to the different orientations of the first light-sensing units SA1, SB1 and the second light-sensing units SA2, SB2, the first light-sensing measurements LA1, LB1 are located at different levels of high levels “Ha” and “Hb”. The third light-sensing units SA3 and SB3 do not correspond to the third light-transmitting areas PA3 and PB3 , so the third light-sensing measurements LA3 and LB3 are at the low level “L”.

As shown in FIG. 3E, in the intelligent assistant mode, the flexible display panel 140 and the first supporting mechanism 110 are both folded backwards, and the first light sensing units SA1 and SB1 correspond to the first light-transmitting areas PA1 and PB1, so A light sensor LA1 and LB1 are located at the high level "H". The second light-sensing units SA2 and SB2 correspond to the second light-transmitting areas PA2 and PB2 , but the ambient light is blocked by the first carrying mechanism 110 , so the second light-sensing measurements LA2 and LB2 are at the low level “L”. The third light-sensing units SA3 and SB3 do not correspond to the third light-transmitting areas PA3 and PB3 , so the third light-sensing measurements LA3 and LB3 are at the low level “L”.

As shown in FIG. 3A, in the reading mode, neither the flexible display panel 140 nor the third carrying mechanism 130 slides upwards, and the first light-sensing units SA1, SB1 do not correspond to the first light-transmitting areas PA1, PB1, so the second A light sensor LA1 and LB1 are located at the low level "L".

The third light-sensing unit SA3 corresponds to the third light-transmitting area PA3, so the third light-sensing level LA3 is at the high level “Hc”. The third light-sensing unit SB3 corresponds to the third light-transmitting area PB3, so the third light-sensing measurement LB3 is at the high level “Hd”. Since the distances between the third light sensing measurement LA3 and the third light sensing unit SB3 from the desktop are different, the third light sensing measurement LA3 and LB3 are at different high levels “Hc” and “Hd”.

In the above example, the relative positions of the first light-transmitting area PA1, PB1, the second light-transmitting area PA2, PB2, and the third light-transmitting area PA3, PB3 remain unchanged, and the first photo-sensing units SA1, SB1 and the second The relative positions of the photo-sensing units SA2 and SB2 remain unchanged, but the relative positions of the second photo-sensing units SA2 and SB2 and the third photo-sensing units SA3 and SB3 follow the sliding of the third carrying mechanism 130 or the flexible display panel 140 And change.
