The electronic device 1000 includes an intelligent thin film layer 1100 and an Integrated Circuit (IC) 1200. The integrated circuit 1200 is used for outputting a control signal. The smart thin film structure 1100 is coupled to the integrated circuit 1200. The at least one touch electrode layer 1140 of the smart film layer 1100 is used for transmitting touch signals according to control signals of the integrated circuit 1200, or the at least one touch electrode layer 1140 of the smart film layer 1100 controls the liquid crystal layer 1130 to present a plurality of transparent states according to control signals of the integrated circuit 1200. The electronic device 1000 further includes a first photo sensor 1300, a second photo sensor 1400, and a backlight plate 1500.

After receiving the light intensity signal, the controller 9000 adjusts the value of the current flowing through the backlight 1500 according to a built-in logic program. When the value of the current flowing through the backlight 1500 is changed, the intensity of the light of the backlight 1500 is changed by the current.

In some embodiments, the light source L includes a point light source, a diffuse light source and a parallel light source, and is not limited to the embodiments of the drawings.

In some embodiments, in a three-dimensional (3D) mode, light emitted from the light guide bars LB at both sides is projected upward through the pattern on the light guide plate 1181. Due to the uneven surface of the light guide plate 1181, the projection angles of the light emitted from the light guide plate 1181 are different. When light enters the eyes, the image or pattern is perceived by the human as having a naked eye 3D effect.

In addition, the pattern on the light guide plate 1181 corresponds to a pixel of the upper element (Cell). Therefore, the light of the light guide plate 1181 is matched with the pixel of the Cell, so that a colored naked-eye 3D image can be formed.

Fig. 8 is a block diagram of a display projection system according to some embodiments of the disclosure. In some embodiments, the display projection system 100 includes an electronic device 1000 and a projector P. The electronic device 1000 includes an intelligent thin film layer 1100, an integrated circuit 1200, and a light sensor 1300. The integrated circuit 1200 is used for outputting a control signal. The photo sensor 1300 is coupled to the integrated circuit 1300 and is used for sensing light intensity. The intelligent thin film layer 1100 is coupled to the integrated circuit 1200, and is configured to transmit a touch signal according to a control signal of the integrated circuit 1200, or is configured to control the liquid crystal layer of the intelligent thin film layer 1100 to assume a plurality of transparent states according to the control signal of the integrated circuit 1200. The projector P is coupled to the integrated circuit 1200 and is configured to project a picture onto the intelligent thin film layer 1100 of the electronic device 1000. The photo sensor 1300 is used for sensing the light intensity of the light source L and controlling a plurality of transparent states of the liquid crystal layer of the smart film layer 1100 according to the light intensity of the light source L via the integrated circuit 1200.

In detail, the light sensor 1300 senses the light intensity of the light source L to generate a light intensity signal to the controller 9000. After receiving the light intensity signal, the controller 9000 controls the voltage controller 9100 according to a built-in logic program. The voltage controller 9100 senses the frequency of the output signal of the controller 9000 in real time to output a voltage to the electronic device 1000, so as to control a plurality of transparent states of the liquid crystal layer of the smart film layer 1100 according to the light intensity signal via the integrated circuit 1200. When the light intensity of the light source L is excessively strong, the voltage controller 9100 controls and reduces the transparency of the liquid crystal layer of the smart film layer 1100 according to the light intensity signal via the integrated circuit 1200 to improve the display effect. On the contrary, when the light intensity of the light source L is too weak, the transparency is increased to make the intelligent thin film layer 1100 in the optimum display state or projection state.

According to the foregoing embodiments, an electronic device and a display projection system are provided, which can reduce the overall thickness of the electronic device through an intelligent film layer, and maintain the electronic device in an optimal display state or projection state through the combination of the display projection system and the intelligent film layer.
