The embodiment of the application provides electronic equipment. The electronic device can be a smart phone, a tablet computer and the like. Referring to fig. 1, the electronic device 100 includes a cover plate 10, a display screen assembly 20, a circuit board 30, and a case 40.
Wherein the cover plate 10 is mounted to the display screen assembly 20 to cover the display screen assembly 20. The cover plate 10 may be a transparent glass cover plate. In some embodiments, the cover plate 10 may be a glass cover plate made of a material such as sapphire.
The display screen assembly 20 is mounted in the housing 40 to form a display surface of the electronic device 100. The display screen assembly 20 serves as a front case of the electronic device 100 and forms an enclosed space with the housing 40 for accommodating other electronic components of the electronic device 100. Meanwhile, the display screen assembly 20 forms a display surface of the electronic device 100 for displaying information such as images, text, and the like.
The circuit board 30 is mounted inside the housing 40 to accommodate the circuit board 30 in the closed space. The circuit board 30 may be a motherboard of the electronic device 100. The circuit board 30 is provided with a grounding point to realize grounding of the circuit board 30. Functional components such as a camera and a processor may be integrated on the circuit board 30.

In some embodiments, display control circuitry is disposed on the circuit board 30. The display control circuit outputs an electrical signal to the display screen assembly 20 to control the display screen assembly 20 to display information.
The housing 40 is used to form the outer contour of the electronic device 100. The housing 40 may be made of plastic or metal. The housing 40 may be integrally formed.
In some embodiments, as shown in FIG. 2, display screen assembly 20 includes a display screen 21, and a sensor assembly 22. Wherein the sensor assembly 22 is disposed at one side of the display screen 21.
It will be appreciated that the sensor assembly 22 is disposed on the inside of the display screen 21. Here, the inner side refers to a side where the display screen 21 is not visible when viewed from the outside of the electronic apparatus 100. That is, the sensor assembly 22 is located inside the electronic device 100.
Wherein the sensor assembly 22 may include an ambient light sensor 221; the ambient light sensor 221 is used for detecting or sensing an external ambient light signal and transmitting sensing information such as ambient light intensity to a processor of the electronic device 100, and the processor controls the brightness of the display screen 21 according to the sensing information.
For example, when the ambient light sensor 221 detects that the ambient light signal becomes weak, the processor may increase the brightness of the display screen 21, and when the ambient light sensor 221 detects that the ambient light signal becomes strong, the processor may decrease the brightness of the display screen 21.
As shown in fig. 2, the ambient light sensor 221 is disposed inside the display screen 21, that is, below the display screen 21.
The display screen 21 is used for displaying information such as images and texts, and the wavelength of the target color light signal in the light signal emitted by the display screen 21 is within the target wavelength range. The target color may include: red, orange, yellow, green, blue, indigo, and purple.
The wavelength of the visible light is 380-780 nm, and the visible light has red, orange, yellow, green, blue, indigo and purple colors respectively. Wherein, the conventional wavelength range of each color light signal is:
the wavelength range of the red light is 770-622 nm, the wavelength range of the orange light is 622-597 nm, the wavelength range of the yellow light is 597-577 nm, the wavelength range of the green light is 597-577 nm, the wavelength range of the blue light and the indigo light is 492-455 nm, and the wavelength range of the purple light is 455-350 nm.
The target wavelength range is located in a conventional wavelength range corresponding to the target color light signal, and the target wavelength range is smaller than the conventional wavelength range and is different from the conventional wavelength range.
For example, when the target color is red, the conventional wavelength range of red light is 770-622 nm, and at this time, the target wavelength range of red light may be 760-630 nm, 750-630 nm, 700-6500 nm, and so on. For another example, when the target color is orange, the conventional wavelength range of the orange light is 622 to 597nm, and at this time, the target wavelength range of the orange light may be 600 to 610nm, 610 to 620nm, and so on.
Referring to fig. 2, a light filtering assembly 23 is further disposed between the ambient light sensor 221 and the display screen 21; specifically, the ambient light sensor 221 has a light-sensing surface 221a, and the light-sensing surface 221a faces the display screen 21 and is used for sensing an ambient light signal incident from the display screen 21; a light filtering member 23 is disposed between the light sensing surface 221a and the display screen 21. In some embodiments, a light filtering member 23 may be disposed on the light sensing surface 221 a.
The light filtering component 23 may filter an external ambient light signal of the light-transmitting display screen 21, and transmit the filtered ambient light signal to the ambient light sensor 221, where the color of the filtered ambient light signal is a target color and the wavelength of the filtered ambient light signal is outside the target wavelength range. For example, the target color is red, the target wavelength range is 760 to 630nm, and the finally obtained filtered optical signal is red, and the wavelength is outside 760 to 630 nm.
It is understood that the optical filter assembly 23 may perform color filtering and wavelength filtering on the ambient light signal to obtain a target color light signal with a wavelength not within the target wavelength range. Therefore, the light filtering component 23 can filter the light signal emitted by the display screen 21, so as to reduce the influence of the light signal of the display screen 21 on the accuracy of ambient light sensing.
For example, the target color is red, and the target wavelength range is 760 to 630nm, for example, the optical filter assembly 23 may filter out other color optical signals except red in the external environment optical signal to obtain a red optical signal, and then filter out a red optical signal with a wavelength in the target wavelength range of 760 to 630nm in the red optical signal to finally obtain a red optical signal with a wavelength not in the range of 760 to 630 nm.
In some embodiments, referring to fig. 3, the light filtering assembly 23 may include a color filter element 231 and a wavelength filter element 232;
the color filter element 231 is configured to filter a light signal, which has a color different from the target color, in the external environment light signal transmitted through the display screen 21, so as to obtain a first light signal;
the wavelength filtering element 232 is configured to filter an optical signal with a wavelength within a target wavelength range in the first optical signal to obtain a second optical signal, and transmit the second optical signal to the ambient light sensor 221.
For example, the target color is orange, and the target wavelength range is 620 to 600nm, for example, first, the color filter element 231 filters out light signals of other colors except orange from the external environment light signal transmitted through the display screen 21 to obtain an orange light signal, at this time, the wavelength filter element 2032 may filter out light signals of the orange light signal with the wavelength within 620 to 600nm, and finally obtain an orange light signal with the wavelength not within 620 to 600 nm.
The color filter element 231 may include a filter having a target color, such as red, green, and the like. The filter having the target color may filter out light signals of other colors than the target color, for example, the green filter only transmits green light signals, and it may filter out light signals of other colors than the green light signals.
Wherein, the wavelength filtering element 232 may include a band pass filter, and the wavelength filtering range of the band pass filter is different from the target wavelength range; the band-pass filter can allow optical signals with wavelengths within a wavelength filtering range to pass through and filter optical signals outside the wavelength filtering range. For example, the wavelength filtering range of the band pass filter is 622 to 650nm, and at this time, the band pass filter can allow the red light signal with the wavelength within 622 to 650nm to pass through, and cut off or filter the red light signal with the wavelength outside 622 to 650 nm.
In some embodiments, the wavelength filtering range of the bandpass filter is within and distinct from the conventional wavelength range of the target color light signal. For example, the target color is red, and the target wavelength range is 700-622 nm, then the wavelength filtering range of the band-pass filter can be 700-750.
In some embodiments, the wavelength filtering range of the bandpass filter and the target wavelength range may constitute a conventional wavelength range of the target color light signal. For example, the target color is orange, the target wavelength range is 597-600 nm, the wavelength filtering range of the band-pass filter can be 601-622 nm, and the two wavelength ranges can form the orange wavelength range of 597-622 nm.
In some embodiments, referring to fig. 4, the display 21 may be a Liquid Crystal Display (LCD), and the display 21 may include a backlight module 211 and a Liquid crystal screen 212;
the backlight module 211 is configured to emit optical signals to the liquid crystal screen 212, where a wavelength of an optical signal of a target color in the optical signals is within the target wavelength range;
the lcd 212 is used for displaying pictures based on the optical signals emitted by the backlight module 211.
The liquid crystal display 211 may include a backlight, a lower polarizer, an array substrate, a liquid crystal layer, a color filter substrate, an upper polarizer, and the like, which are stacked in sequence.
The backlight module 211 may include a light source, a light guide plate, a reflective sheet, an optical film, and the like, wherein the wavelength of the target color light signal in the light signal emitted by the light source is within the target wavelength range. The light source can be a light emitting device such as an LED lamp.
In some embodiments, the display screen 21 may also be an Organic Light-Emitting Diode (OLED) display screen or the like; when the display panel 21 is an organic light emitting diode display panel, the display panel 21 may include a base layer, an anode, an organic layer, a conductive layer, an emission layer, a cathode, and the like, which are sequentially stacked.
Because it is inboard with ambient light sensor setting display screen, if the display screen is bright when the screen, then the luminance of display screen itself can influence the detection of light sense, and the light sense value that detects when the display screen is bright at this moment is in fact to be greater than real external light sense value, leads to ambient light sensor sensitization accuracy relatively poor.
In the embodiment of the present application, the wavelength of a certain color light signal in the light signals emitted by the display screen 21 is within a target range, and before the ambient light sensor 221 receives the external ambient light signal, the light signal may be subjected to color and wavelength filtering to obtain a certain color light signal whose wavelength is not within the target range, that is, a special wavelength color light signal, and the brightness of the display screen 21 is controlled based on the special wavelength color light signal. This scheme can filter the light signal that display screen 21 sent among the environment light signal to realize controlling the luminance of display screen 21 based on certain special wavelength colour light signal, can get rid of the luminance of display screen 21 and to the influence of environment light sensor's light sense value, promoted environment light sensor sensitization accuracy, and the accuracy of display screen 21 brightness control.

When the detection signal a contacts an external object 200 (e.g., a user's face), a reflected signal B is generated. The reflected signal B enters the signal receiver 222B through the display screen 21.
After receiving the reflected signal B, the signal receiver 222B may output the received signal to a processor of the electronic device 100 for processing, so as to control the display screen of the electronic device 100 to turn off or turn on.
