Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Before describing the electronic device and the photosensitive module thereof of the embodiments of the present application, a conventional electronic device and a photosensitive module thereof will be described.

Referring to fig. 1, the electronic device includes a display panel 10 and a photosensitive module 20, wherein the photosensitive module 20 is disposed on one side of the electronic device. The photosensitive module 20 includes a first optical sensor 201 and a second optical sensor 202, the first optical sensor 201 is disposed on one side of the second optical sensor 202, and there is no spacing structure between the first optical sensor 201 and the second optical sensor 202. In order to avoid the mutual interference of the light rays on the first light sensor 201 and the second light sensor 202, the distance between the first light sensor 201 and the second light sensor 202 is large, which results in a large volume of the photosensitive module 20. When the photosensitive module 20 with a larger volume is disposed in the electronic device, the internal space of the electronic device will be wasted.

Based on the above problem, the utility model provides an electronic equipment and sensitization module 20 thereof.

Referring to fig. 2, the electronic device includes a display panel 10 and a photosensitive module 20, wherein the photosensitive module 20 is disposed on a side of the display panel 10 opposite to a display side. The display panel 10 typically includes a polarizer, which is used to eliminate the reflection of ambient light in the display panel 10 and to polarize and filter the incident ambient light. The display panel 10 includes a light emitting surface and a back surface opposite to the light emitting surface. The polarizer is disposed on one side of the light-emitting surface, and the photosensitive module 20 is disposed on one side of the back surface. The photosensitive module 20 will be described as follows.

The photosensitive module 20 includes a substrate 205, a first photosensor 201, a second photosensor 202, a baffle 203 and a quarter-wave plate 204, the baffle 203 is disposed on the substrate 205, the first photosensor 201 and the second photosensor 202 are both disposed on the substrate 205, the first photosensor 201 and the second photosensor 202 are respectively disposed on two sides of the baffle 203, the quarter-wave plate 204 is fixed between the display panel 10 and the second photosensor 202, and a projection of the quarter-wave plate 204 on the substrate 205 covers a projection of the second photosensor 202 on the substrate 205. It will be appreciated that the baffle 203 is upstanding from the base plate 205. A circuit board is further disposed on the substrate 205, and the first optical sensor 201 and the second optical sensor 202 are electrically connected to the circuit board. The first optical sensor 201 is connected to the circuit board by a conductive adhesive or gold wire. The second optical sensor 202 is connected to the circuit board by a conductive adhesive or gold wire. The circuit board may be a flexible circuit board. The substrate 205 is made of plastic, resin, or ceramic. The baffle 203 is a silicone baffle 203.

In this application, first light sensor 201 and second light sensor 202 locate the both sides of baffle 203 respectively, first light sensor 201 and second light sensor 202 carry out the interval through baffle 203, this makes the distance between first light sensor 201 and the second light sensor 202 can set up lessly, light on the first light sensor 201 and the light on the second light sensor 202 also can not mutual interference, first light sensor 201 and second light sensor 202 mutually support and can accurately acquire the ambient light size, moreover, because the distance between first light sensor 201 and the second light sensor 202 is less, the volume of sensitization module 20 is less. When the photosensitive module 20 with a smaller volume is applied to an electronic device, the occupied volume of the electronic device is smaller, and the space is saved.

Specifically, after the ambient light enters the display panel 10 from the outside through the polarizer, part of the ambient light is reflected by the display panel 10. The reflected light cannot be emitted from the display panel 10 due to the action of the polarizer, so as to achieve the purpose of eliminating the reflection of the light by the polarizer. And another portion of the light passes through the display panel 10 and exits the rear surface. The first light sensor 201 is used to receive the portion of light, which is a light path of the ambient light propagating toward the first light sensor 201 in the photosensitive module 20 of the present application. Further, the first light sensor 201 is also used for receiving light generated by the display panel 10 itself. It will be appreciated that the electronic device will display images to the user via the display panel 10. The display panel 10 itself emits light. The light emitted from the display panel 10 is also emitted from the back surface and reaches the position of the first light sensor 201. Therefore, in the photosensitive module 20 of the present application, the first light sensor 201 detects the ambient light and the light emitted from the display panel 10 at the same time.

The second light sensor 202 is disposed on one side of the first light sensor 201, and the two are spaced by a baffle 203. A quarter wave plate 204 is also provided between the second light sensor 202 and the display panel 10. That is, the light emitted from the back surface needs to pass through the quarter-wave plate 204 before reaching the second light sensor 202. Unlike the first light sensor 201, after passing through the polarizer, the ambient light is filtered according to the polarization direction of the light, that is, only the light polarized toward the first direction is allowed to pass through. When passing through the quarter-wave plate 204, the light transmitted by the polarizer is filtered again according to the polarization direction of the light, and only the light polarized towards the second direction is allowed to pass through. That is, by matching the first direction and the second direction, for example, the first direction and the second direction are perpendicular, most of the ambient light can be blocked by the polarizer and the quarter-wave plate 204. In general, the polarizer and quarter wave plate 204 cooperate to block ambient light from passing through the polarizer and quarter wave plate 204 continuously. In theory, no ambient light passes through the quarter wave plate 204 to the second light sensor 202. While light generated by the display panel 10 itself may pass through the quarter-wave plate 204 directly to the second light sensor 202. That is, the second light sensor 202 can only receive the light generated by the display panel 10 by the cooperation of the polarizer and the quarter-wave plate 204.

Since the first light sensor 201 and the second light sensor 202 are spaced apart by the barrier 203, when the first light sensor 201 and the second light sensor 202 are close to each other, the light generated by the display panel 10 received by the first light sensor 201 and the second light sensor 202 is nearly uniform. Therefore, the first light sensor 201 may receive the ambient light, which causes a difference between the intensity of the light sensed by the first light sensor 201 and the intensity of the light sensed by the second light sensor 202. Therefore, by calculating the light ray difference value received by the first light sensor 201 and the second light sensor 202 at the same time, the current ambient light can be calculated, so as to identify the current environment and scene of the electronic device. Furthermore, the electronic device can automatically adjust the display brightness of the display panel 10 according to the current ambient light intensity, thereby improving the user experience. The photosensitive module 20 can also perform distance detection based on the intensity of ambient light, and automatically turn off the screen when the user uses the electronic device to answer a call.

Moreover, this application sensitization module 20 is because the setting and the cooperation of first light sensor 201 and second light sensor 202 for display panel 10 also can sense ambient light under the condition of not trompil, has replaced the structure of current trompil on display panel 10, thereby has guaranteed electronic equipment's outward appearance uniformity, has increaseed the possibility that electronic equipment realized the full screen, has promoted user experience. Therefore, the electronic equipment of the application not only can keep the appearance consistency, but also can reduce the volume of the electronic equipment occupied by the photosensitive module 20.

It should be noted that the wavelength band of the ambient light is not strictly limited in the present application. That is, in the present embodiment, the first light sensor 201 and the second light sensor 202 may sense visible light at the same time, or the first light sensor 201 and the second light sensor 202 may sense infrared light at the same time. It can be understood that, as long as the light wavelength bands sensed by the first light sensor 201 and the second light sensor 202 are the same, the light intensity difference can be obtained by matching and comparing the two, and the intensity of the external environment light can be identified based on the difference. And products such as current polaroid, optical sensor all can reach the function that covers 300 ~ 1100nm wavelength light simultaneously, consequently this application sensitization module 20 can only be used for monitoring visible light or infrared light, also can monitor visible light and infrared light simultaneously, as long as first optical sensor 201 and second optical sensor 202 are unanimous at the light wavelength of same monitoring moment, all can reach the function of response ambient light intensity.

On the other hand, the type of the display panel 10 needs to be transparent to the ambient light to achieve the function of emitting the ambient light into the first light sensor 201. In the current mainstream display technology, the oled panel can achieve corresponding effects. Of course, the electronic module of the present application is not limited to the display panel 10 using oled technology, and as long as the Qled panel and the panel using other display technologies that may appear in the future can achieve the ambient light penetrating function, the electronic module of the present application can be used as the display panel 10 of the electronic device of the present application, and achieves the effect similar to oled panel. Further, since the display panel 10 can penetrate the ambient light at any position of the light emitting surface, in the electronic device of the present application, the first light sensor 201 and the second light sensor 202 can be disposed at any position relative to the light emitting surface. Since holes do not need to be punched in the display panel 10, the first and second

light sensors

201 and 202 are disposed at any positions without affecting the display effect of the display panel 10.

In a specific embodiment, a receiving space is formed in the substrate 205, the baffle 203 is disposed in the receiving space to divide the receiving space into a first sub-space 205a and a second sub-space 205b, the first light sensor 201 is disposed in the first sub-space 205a, and the second light sensor 202 is disposed in the second sub-space 205 b. It is understood that the substrate 205 may be directly grooved to directly form the first subspace 205a and the second subspace 205b, and the baffle plate 203 and the substrate 205 are formed together; or the base plate 205 is notched to form a receiving space, and the baffle plate 203 is arranged in the receiving space to divide the receiving space into a first subspace 205a and a second subspace 205 b. Circuit boards are arranged in the first subspace 205a and the second subspace 205b, and the first optical sensor 201 and the second optical sensor 202 are electrically connected with the circuit boards. Therefore, the baffle 203 is disposed in the accommodating space for isolating the light in the first subspace 205a and the light in the second subspace 205b, and light leakage generated between the first subspace 205a and the second subspace 205b is avoided, which affects the light sensing accuracy of the first light sensor 201 and the second light sensor 202.

In a specific embodiment, the substrate 205 includes a bottom plate 2052 and a side plate 2051 connected to the bottom plate 2052, the bottom plate 2052 and the side plate 2051 form a receiving space, the bottom plate 2052 is a circuit board, the baffle 203 is disposed in the receiving space to divide the receiving space into a first sub-space 205a and a second sub-space 205b, the first optical sensor 201 is disposed in the first sub-space 205a, and the second optical sensor 202 is disposed in the second sub-space 205 b. Thereby, bottom plate 2052 sets up to the circuit board, has avoided setting up the circuit board again in accommodating space, practices thrift the space, can reduce sensitization module 20's height, and then reduces sensitization module 20's volume, practices thrift the cost moreover. Specifically, the side plates 2051 are disposed on the edge of the bottom plate 2052, the baffle 203 is disposed in the accommodating space and supported on the bottom plate 2052, the baffle 203 and a part of the side plates 2051 form a first subspace 205a, and the baffle 203 and another part of the side plates 2051 form a second subspace 205 b.

The first subspace 205a and the second subspace 205b are both open towards the display panel 10 for the entrance of light rays. Light generated by the display panel 10 enters the first subspace 205a and the second subspace 205b to be received by the first light sensor 201 and the second light sensor 202, respectively, and ambient light enters the first subspace 205a to be received by the first light sensor 201. The baffle 203 is further used for isolating light rays in the first subspace 205a and the second subspace 205b, and light leakage generated between the first subspace 205a and the second subspace 205b is avoided, so that the light sensing accuracy of the first light sensor 201 and the second light sensor 202 is not affected.

The photo-sensing module 20 further includes a strengthening plate 207, the strengthening plate 207 is fixed on the substrate 205 in a lap joint manner, the strengthening plate 207 is located between the display panel 10 and the first photo-sensor 201 and between the display panel 10 and the second photo-sensor 202, and the quarter-wave plate 204 is fixed on the strengthening plate 207. Specifically, the reinforcing plate 207 may be fixed to a side plate of the base plate 205 in a lap joint manner to cover the first subspace 205a and the second subspace 205 b. The reinforcing plate 207 may enhance light transmittance, increase a viewing angle, or make light uniform.

The reinforcing plate 207 is a light intensifying plate or a light homogenizing plate, or the reinforcing plate 207 is a combination of a light intensifying plate and a light homogenizing plate. Thus, when the reinforcing plate 207 is a light reinforcing plate, the light transmittance of light can be enhanced, the viewing angle can be increased, and the incident amount of the ambient light and the incident amount of the light of the display panel 10 reaching the first light sensor 201 can be increased, and the incident amount of the light of the display panel 10 reaching the second light sensor 202 can be increased. Therefore, when the light entering amount of the ambient light is increased, the size of the acquired ambient light is more accurate. When the reinforcing plate 207 is a light homogenizing plate, the setting of the light homogenizing plate can make the ambient light entering the first optical sensor 201 uniform, the light entering the display panel 10 of the first optical sensor 201 is uniform, the light entering the display panel 10 of the second optical sensor 202 is uniform, and the intensity of the ambient light is easier and more accurate. When the reinforcing plate 207 is a combination of a light intensifying plate and a light homogenizing plate, the functions of the light intensifying plate and the light homogenizing plate can be simultaneously provided. In a specific embodiment, the baffle 203 extends to contact the reinforcement plate 207 such that the reinforcement plate 207 completely seals the first subspace 205a and the second subspace 205 b. Thus, the reinforcing plate 207 is in contact with both the side plate and the baffle 203, and the reinforcing plate 207 completely seals the first subspace 205a and the second subspace 205b, thereby completely avoiding light leakage between the first subspace 205a and the second subspace 205b and influencing the light sensing accuracy of the first light sensor 201 and the second light sensor 202.

The quarter-wave plate 204 is clamped in the position, so that the thickness occupied by the quarter-wave plate 204 can be omitted, and the thickness of the photosensitive module 20 can be reduced. It is understood that the surface of the quarter-wave plate 204 is flush with the surface of the strengthened plate 207, or there is a height difference between the surface of the quarter-wave plate 204 and the surface of the strengthened plate 207.

In one specific embodiment, the stiffener plate 207 is a uniform plate, and the quarter wave plate 204 is stacked on the stiffener plate 207. The reinforcing plate 207 is provided as an equal-thickness plate so that the intensity of light entering the display panel 10 on the first light sensor 201 and the second light sensor 202 is the same, and thus, the intensity of ambient light can be more accurately acquired.

In a specific embodiment, the projection of the quarter wave plate 204 on the substrate 205 coincides with the projection of the second light sensor 202 on the substrate 205. Therefore, when the projection of the quarter-wave plate 204 on the substrate 205 is overlapped with the projection of the second light sensor 202 on the substrate 205, not only the ambient light cannot reach the second light sensor 202, but also the material of the quarter-wave plate 204 is saved, and the cost is saved. It is understood that the quarter-wave plate 204 can be stacked on the top surface of the second photosensor 202 to reduce the thickness of the photosensitive module 20, and thus the thickness of the electronic device; alternatively, the quarter wave plate 204 is spaced from the second photosensor 202, which makes the position of the quarter wave plate 204 more flexible.

In a specific embodiment, the quarter-wave plate 204 covers the second subspace 205 b. Thus, the external ambient light cannot enter the second subspace 205b at all, the light in the second subspace 205b is only the light generated by the display panel 10, and the second light sensor 202 can only receive the light generated by the display panel 10, which makes the magnitude of the obtained ambient light more accurate. It will be appreciated that the quarter-wave plate 204 may be secured in a variety of ways, either by a bracket, or directly overlapping the substrate 205, or overlapping the stiffener plate 207 as described above.

The technical features of the above embodiments may be arbitrarily combined, and for the sake of brief description, all possible combinations of the technical features in the above embodiments are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above examples only represent some embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
