In the related art, a Photodiode (PD) array for sensing ambient light in an ambient light sensor is located in the same plane as an Active Front End (AFE) for signal processing and is located on the front surface of a mobile terminal. Thus, the ambient light sensor becomes an obstacle for the mobile terminal to move to the full screen.
The embodiment of the present disclosure provides a mobile terminal, which can solve the above technical problem and improve the screen occupation ratio of the mobile terminal.
Fig. 1 is an exploded view of a mobile terminal according to an exemplary embodiment. Fig. 2 is a cross-sectional schematic diagram of a mobile terminal shown in accordance with an example embodiment. As shown in fig. 1 to 2, a mobile terminal 1 of the embodiment of the present disclosure includes: a center housing 11, a display panel 12, and an ambient light sensor 13.
As shown in fig. 1, the display panel 12 is provided on the center frame case 11 from the front, and a gap portion 14 is provided between the display panel 12 and the center frame case 11. The ambient light sensor 13 is provided in the gap portion 14.
As shown in fig. 2, the ambient light sensor 13 includes a photosensitive element array 131 and a processing chip 132. The photosensitive element array 131 is electrically connected to the processing chip 132. The photosensitive element array 131 is disposed on the display panel 12 and faces one surface of the middle frame housing 11, and a sensing direction of the photosensitive element array 131 faces the display panel 12. The processing chip 132 is disposed on a surface of the photosensitive element array 131 away from the display panel 12.
In the embodiment of the disclosure, the ambient light sensor is arranged in the gap between the display panel and the middle frame shell, so that the ambient light sensor can be used for sensing the light intensity of the environment where the mobile terminal is located, a larger space can be provided for the display panel, and the screen occupation ratio of the mobile terminal can be improved.
The gap shown in fig. 1 is only one embodiment of the gap. In practical applications, since there may be a plurality of gap portions or a plurality of gap portions between the display panel and the middle frame housing 11, the position of the ambient light sensor may be arranged according to specific requirements.
In one embodiment, the photosensitive element array 131 can be attached to the display panel 12.
As shown in fig. 2, in an embodiment, the mobile terminal 1 may further include a light scattering module 15, where the light scattering module 15 is disposed between the photosensitive element array 131 and the display panel 12. The light scattering module 15 can scatter the incident light entering the light scattering module 15, so that the incident light entering the surface of the light scattering module 15 according to an incident angle is subjected to diffuse reflection and becomes soft, the current signal generated by the photosensitive element array 131 is weakened, a larger current signal is prevented from being generated when the incident light entering according to a certain incident angle is directly incident on the photosensitive element array 131, and the response to the incident light angle is improved.
In one embodiment, the light diffusion module 15 may include at least one diffuser (not shown), and the diffuser may diffuse the incident light. In one embodiment, the light diffusion module may further include at least one aperture, and the light diffusion sheets are alternately arranged with the aperture. The aperture can absorb light except for the direction in which the photosensitive element array 131 faces the display panel, improving the accuracy of ambient light detection. In an exemplary embodiment, the light scattering module comprises 3 light scattering sheets and two black apertures, and the light scattering sheets, the black apertures, the light scattering sheets, and the black apertures are sequentially arranged from the display panel 12 to the photosensitive element array 131.

The display panel 12 is provided on the case main body 111 from the front, and the rear case 12 is covered on the bezel 112 from the rear.
As shown in FIG. 1, in one embodiment, the bezel 112 includes a top bezel 113; the ambient light sensor 13 is located on the display panel 12 at a side close to the top bezel 113. In practical applications, the ambient light sensor 13 may be arranged beside an earpiece of the mobile terminal. Therefore, when the user normally holds the mobile terminal, the ambient light sensor 13 is located at the top of the mobile terminal, so that inaccurate ambient light detection caused by the fact that the user blocks light in the process of using the mobile terminal can be avoided.
As shown in FIG. 3, in one embodiment, the array of photosensitive elements 131 is a photodiode array. The photodiode array is an array composed of a plurality of photodiodes D. The photodiode D is used for converting the detected optical signal into an electrical signal for subsequent processing. Specifically, the photodiode D may convert the detected light signal into a current signal.
As shown in fig. 3, in one embodiment, the processing chip 132 includes an amplifier AMP, a resistor R, and an analog-to-digital converter ADC. The photodiode D in the photodiode array 131 is electrically connected to an input terminal of the amplifier AMP, and an output terminal of the amplifier AMP is electrically connected to the analog-to-digital converter ADC. One end of the resistor R is connected between the output end of the amplifier AMP and the analog-to-digital converter ADC, and the other end of the resistor R is grounded and can also be connected with the lowest potential of the mobile terminal. The amplifier AMP is configured to amplify the electrical signal output by the photodiode D to enable the analog-to-digital converter ADC to sample. The current signal output by the amplifier AMP can be converted into a voltage signal by the resistor R, and the voltage signal is sampled and converted into a series of binary 0 and 1 signals by the analog-to-digital converter ADC and output to the bus interface and the logic control LC. And the bus interface and the logic control LC finish the conversion from data to a transmission protocol, and encapsulate the acquired data into related transmission protocol data to be transmitted to the application processor AP. And completing the system conversion at the application processor AP side, and if the application processor AP side detects that the received data is smaller, controlling the amplifier AMP by sending a command, and adjusting the gain of the amplifier to enable the amplification factor of the photocurrent signal to be adjusted in a self-adaptive manner. Wherein the application processor AP is electrically connectable to the amplifier AMP via the glass cover plate CG. In particular, the application processor AP may be electrically connected to the amplifier AMP via wiring in the glass cover plate CG.
In addition, as shown in fig. 1, the rear case 17 is fitted with the case main body 14 and can be fitted with at least a battery 18. The mobile terminal 1 in the embodiment of the present disclosure may be a full-screen mobile phone or an ultra-high-screen mobile phone. Wherein, the screen of the full screen mobile phone accounts for 100%. In the embodiment of the present disclosure, the display panel may be an OLED display panel.
