Problems solved by technology

[0009] Since the above two modules are independent devices, including circuit substrates respectively, it not only increases the difficulty of the structural design of the electronic device, but also takes up a large volume, which is not conducive to the integration of electronic devices and the miniaturization of electronic equipment. ultimately increased production costs
[0010] In addition, in the prior art, the three-in-one light-sensing module 30 can also be replaced by a two-in-one light-sensing module. Compared with the three-in-one light-sensing module 30, the two-in-one light-sensing module The measurement module does not include an infrared emitting device (such as an infrared light-emitting diode), so an additional infrared emitting device needs to be added, which will further increase the volume of the device and increase the production cost

Embodiment 1

[0041] refer to figure 2 As mentioned above, this embodiment provides a handheld electronic device, including an image sensor module 100 and a display screen 200, wherein: the image sensor 100 includes:

[0042] Circuit substrate 110;

[0043] An image sensor 120 located on the circuit substrate 110 and electrically connected to the circuit substrate 110, the image sensor 120 includes a photosensitive unit 121;

[0044] An optical lens 130, located above the image sensor 120, and the optical center of the optical lens 130 is on the same axis as the photosensitive center of the photosensitive unit 121;

[0045] The light emitting module 150 is located on the circuit substrate 110 around the image sensor 120, and includes an infrared light emitting diode 151 for emitting infrared light;

[0046] A bandpass filter 140, located above the optical lens 130, is used to transmit visible light in the infrared light and ambient light into the optical lens 130;

[0047] The photosens...

Embodiment 2

[0073] refer to image 3 As shown, this embodiment provides a handheld electronic device, which is compatible with figure 2 In comparison, the band-pass filter 140 is located on the image sensor 120, the optical lens 130 is located on the band-pass filter 140, and the rest are the same as in the first embodiment.

[0074] In this embodiment, all the light that enters the surface of the optical lens 130 is first collected, and then the band-pass filter 140 is used to filter and remove the infrared light emitted by the infrared light-emitting diode 151 and the light other than visible light in the ambient light. Finally, the light signal detected by the photosensitive unit 121 is the same as that in the first embodiment.

[0075] This embodiment also omits the three-in-one light sensing module, and at the same time integrates the functions of the infrared proximity sensor and the ambient light detection sensor into the image sensor module, realizing a high degree of integratio...

Abstract

Disclosed are an imaging sensor module and a handheld electronic device. The imaging sensor module comprises a circuit substrate, an imaging sensor of a light-sensing unit, an optical lens, an illuminating module and a band-pass filtering sheet, wherein the optical lens is placed above the imaging sensor and the optical center of the optical lens is on the same axis with the light-sensing center of the light-sensing unit; the illuminating module is placed on the circuit substrate on the periphery of the imaging sensor and comprises an infrared light emitting diode; the band-pass filtering sheet is placed above the optical lens or between the optical lens and the imaging sensor and is used for enabling visible light in infrared light and ambient light to shot in the optical lens; the light-sensing unit detects the visible light and the infrared light, transforms the obtained light signal into an electrical signal and transmit the electrical signal to the circuit substrate. The handheld electronic device comprises the imaging sensor and a display screen, wherein the display screen comprises a backlight source. Light intensity of the backlight source is adjusted through the circuit substrate according to the electrical signal corresponding to the visible light, and the backlight source is turned off according to the electrical signal corresponding to the infrared light. By means of the imaging sensor module and the handheld electronic device, size of the device is reduced and production cost is lowered.

Description

technical field [0001] The invention relates to the technical field of integrated circuits, in particular to an image sensor module and a handheld electronic device. Background technique [0002] With the development of hand-held electronic devices such as smartphones and tablet computers, image sensors for taking pictures or videos have become the basic configuration of the above-mentioned electronic devices, and touch-type operations gradually replace button-type operations. Taking the touch-type mobile phone as an example, since the user's face is close to the touch screen of the mobile phone when the user is talking, the mobile phone will be falsely triggered. Therefore, an infrared (Infrared, IR) proximity sensor including an infrared emitting device and an infrared receiving device is usually installed on the mobile phone. , when the infrared proximity sensor detects that the light is blocked, the mobile phone thinks that the face is close to the touch screen, so as to...
