[0042] The cover plate assembly according to the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0043] like Figures 1 to 13 As shown, the cover assembly according to the embodiment of the present invention includes a cover body 10 and a plurality of photosensitive modules 20 .

[0044] Specifically, a plurality of photosensitive modules 20 are spaced apart and distributed on one side of the cover, and the size of at least one photosensitive module 20 is different from the size of the remaining photosensitive modules 20; each photosensitive module 20 includes: a pixel unit 21, and the pixel unit 21 corresponds to the position of the cover body 10.

[0045] In other words, the cover assembly according to the embodiment of the present invention is mainly composed of a cover body 10 and a plurality of photosensitive modules 20. The plurality of photosensitive modules 20 can be spaced apart and distributed on one side of the cover, such as Figure 3 and Figure 6As shown, multiple photosensitive modules 20 can cover the entire area of ​​the cover plate, supporting full-screen ambient light detection. And the size of at least one photosensitive module 20 is different from the size of the other photosensitive modules 20, which can play a role in adjusting the light intensity of the sensing module. Each photosensitive module 20 includes: a pixel unit 21, and the pixel unit 21 corresponds to the position of the cover plate body 10.

[0046] In the present utility model, if Figure 1 and Figure 2 As shown, the main design of the photosensitive module 20 can adopt the pixel design of mobile phone cameras. By adopting semiconductor technology and following the semiconductor process, there is no need to prevent interference between photosensitive materials to make isolation structures, and the spacing between photosensitive pixels can be increased according to the process conditions. After the pixel is made, the photosensitive pixels (pixel units 21) are separated into individual units by laser cutting (see Figure 3 ). Then they are scattered and attached to the cover glass, and the electrodes of the photosensitive pixels are connected through transparent electrodes.

[0047] Therefore, according to the cover assembly of the embodiment of the utility model, the photosensitive module 20 is integrated to separate the photosensitive module 20 from the screen, without affecting the frame size design of the screen. At the same time, the photosensitive area of ​​the photosensitive module 20 is larger than that of the design integrated in the display screen, supporting full-screen ambient light detection with higher accuracy and better precision.

[0048] According to an embodiment of the present invention, a plurality of photosensitive modules 20 are arranged in a row on the cover body 10 , and each photosensitive module 20 is provided with a color film 22 , and the color of at least one color film 22 is different from the colors of the other color films 22 .

[0049] That is to say, Figure 6 and Figure 7 As shown, a plurality of photosensitive modules 20 can be arranged in a row on the cover body 10, and each photosensitive module 20 is provided with a color film 22, and the color of the color film 22 can be different, so as to ensure that the color of at least one color film 22 is different from the color of the other color films 22. In the present invention, as Figure 3 As shown, in order to detect the ambient light intensity and color temperature, photosensitive pixels covered with red, green and blue color films 22 can be used. Or, in order to detect the intensity of specific ambient light, a color film 22 of a special color can be covered on the photosensitive pixel. In this way, the intensity of light of a specific color can be detected, and it can be applied to respond to light of a specific color. Furthermore, a color film 22 that only transmits a single wavelength can be used as a covering material (such as quantum dots), so that the detection of light of a specific wavelength can be achieved, avoiding interference from light of other wavelengths.

[0050] In the present invention, the pixel size is much smaller than the pixel size in the camera. Therefore, the yellow light process can be directly used to directly make dispersed pixel light sensors on the cover glass (cover body 10). Since the pixel size of the present invention is much smaller than the camera light sensor, the yellow light process does not require pixel transfer, and the pixel circuit layout is simpler.

[0051] According to one embodiment of the utility model, the size of each pixel unit 21 is less than 80μm. In order to ensure the transparency of the cover body 10, the size of the pixel unit 21 distributed in the AA area can be less than 80um, and a certain distance is maintained between the pixel unit 21 and the pixel unit 21. In order to increase the photosensitivity accuracy and photosensitivity. The utility model can output photosensitivity values ​​by connecting multiple sub-pixels (RGB or RRGGBB, etc.) in series, which can achieve higher accuracy than the single pixel in the camera sensor to obtain photosensitivity values. The light-sensing signal acquisition mode is consistent with that in the camera. Therefore, the micro-lens structure can be eliminated in the pixel structure design, which greatly simplifies the manufacturing process.

[0052] According to an embodiment of the present invention, the photosensitive module 20 further includes: a plurality of electrodes, which are arranged at intervals in the color film 22 or the photosensitive area of ​​the photosensitive module 20 to construct the photosensitive module 20 into a capacitive photosensitive sensor.

[0053] In other words, Figures 6 to 13 As shown, the photosensitive module 20 also includes a plurality of electrodes, which may be an X electrode 23, a Y electrode 24, and a ground electrode 25. The plurality of electrodes are spaced apart and distributed in the photosensitive area of ​​the color filter 22 or the photosensitive module 20, so that the photosensitive module 20 is constructed as a capacitive photosensitive sensor. Figure 4 and Figure 5 As shown in FIG, a capacitive photosensitive pixel can use a photosensitive material as a medium between capacitor electrodes. When ambient light irradiates the photosensitive material, a photosensitive current is generated. Figure 4 First, the capacitor is charged with the X scanning line 31, and after charging is completed, the capacitor is detected by the Y scanning line 32. Due to the formation of photosensitive current, the capacitance of the capacitor will be reduced. The greater the light intensity, the greater the leakage current. The Y scanning line 32 may obtain signal values ​​of different sizes, and then output the light intensity signal value through the peripheral amplifier and A / D converter.

[0054] Similarly, the capacitance value may be changed due to the current formed by the photosensitive material after being illuminated, and the X-direction position may be located through the X scanning line 31, and the Y-direction position may be located through the Y scanning line 32. At the same time, the illumination intensity may be confirmed according to the capacitance value change. This application method may support more photosensitive pixel applications and reduce the number of wiring. Both application methods are compatible with touch screen design.

[0055] According to an embodiment of the present invention, a translucent material piece 26 is disposed between the cover plate and each corresponding pixel unit 21 , and at least one translucent material piece 26 has a different transparency from the other translucent material pieces 26 .

[0056] That is to say, Figure 7 As shown, a translucent material piece 26 may be provided between the cover plate and each corresponding pixel unit 21, and at least one translucent material piece 26 has a different transparency from the other translucent material pieces 26. In order to further increase the photosensitivity accuracy and photosensitivity range. The utility model integrates photosensitizing pixels of different sizes in the cover plate, or makes a translucent layer with different transmittance values ​​on the photosensitizing pixels, so that some pixels are used for the detection of high brightness state, some pixels are used for the detection of medium brightness state, and some pixels are used for the detection of low brightness state.

[0057] According to one embodiment of the utility model, Figures 8 to 13 As shown, the photosensitive module 20 also includes: a light shielding layer 27, which is arranged at two opposite side regions of the pixel unit 21. In order to reduce the interference of stray light, the utility model can add a black light absorbing layer (light shielding layer 27) around the pixel, and the light shielding layer 27 can be made of black resin material.

[0058] In order to reduce the background noise (including the touch signal in the capacitive photosensitive pixel), the utility model can set calibration pixels and arrange the calibration pixels around the regular pixels. The calibration pixels add the pixels of the light shielding layer 27 to the photosensitive pixels of the whole vehicle. Because the photosensitive module 20 cannot be illuminated by light, the signal generated is the background noise. Therefore, the signal value of the regular pixel minus the signal value of the calibration pixel can obtain the required ambient light signal.

[0059] In some specific embodiments of the present invention, the photosensitive module 20 further includes: a light guide structure 28, which is disposed between the color film 22 and the cover body 10. Two opposite sides of the light guide structure 28 are provided with light guide grooves 29. The pixel unit 21 is disposed obliquely relative to the cover body 10.

[0060] That is to say, Fig.11 As shown, the photosensitive module 20 further includes a light guide structure 28, which is disposed between the color film 22 and the cover body 10. Light guide grooves 29 are disposed on two opposite sides of the light guide structure 28. The pixel unit 21 can be disposed obliquely relative to the cover body 10.

[0061] In order to realize the detection of ambient light at different angles, the utility model designs angle light sensing pixels. In the utility model, four types of angle light sensing pixel design schemes are provided. For example, the design description is based on the capacitive photosensitive pixel. The photosensitive pixels similar to the camera CMOS can also adopt the modified structure scheme. The first type, such as Figure 8 As shown in FIG. 1 , a black light-guiding structure 28 is designed between the pixel unit 21 and the cover body 10. The structure can absorb light from other angles and only transmit light in the light transmission direction to the photosensitive pixel. The photosensitive pixel and the cover body 10 are directly filled with transparent materials. The second type is to add a transparent light-guiding structure 28 between the photosensitive pixel and the cover body 10, and dye the periphery of the structure black. The third type is as follows: Fig.12 and Fig.13 As shown, the photosensitive pixels are attached to the cover body 10. The fourth type is to design the light receiving surface of the photosensitive pixel to be an inclined surface. Angle light sensing pixels can collect ambient light signals at required angles and output ambient light intensity signals at different angles.

[0062] In order to achieve that the intensity of ambient light can be obtained at different positions of the display screen, the utility model can arrange the photosensitive pixels at various positions of the display screen. The photosensitive module 20 can also be arranged in the ink area or BM area. Arranging it in the ink area can further increase the size of a single photosensitive pixel and reduce the density of photosensitive pixel components. The ink area also needs to increase the calibration pixels. The light shielding layer 27 on the calibration pixel can be replaced by ink or BM, and the ink or BM on the photosensitive pixel needs to be removed. Avoid shading.

[0063] The utility model realizes that the ambient light is irradiated onto the display screen, and the display screen adjusts the brightness and display color temperature of the display screen according to the intensity of the irradiated ambient light and the color temperature signal, so that the driver can observe the display screen more comfortably.

[0064] The cover assembly of the utility model can scatter photosensitive sensors on the display cover, and can collect ambient light signals within the surface of the display. In conjunction with display technology that supports local dimming (such as Mini-LED LCD, OLED, Micro-LED, etc.), the brightness of the display can be high in the illuminated part and low in the unilluminated part.

[0065] The utility model can also realize the angular distribution collection of ambient light intensity, can realize the collection of light that can irradiate the driver, and ignore the light that will not affect the driver, so that the screen dimming is more suitable for the driver. And the photosensitive sensor (photosensitive module 20) can be integrated on the windshield, and with the light signal collection solution for specific wavelengths of the present invention, the purpose of using specific light to control the vehicle can be achieved.

[0066] In summary, the cover assembly of the utility model does not affect the frame size of the screen, supports full-screen ambient light detection, can realize angle light collection, and can obtain the intensity of ambient light incident at different angles. It also realizes the brightness collection of light of different colors and wavelengths. It can be used as a signal collection device to realize specific light control.

[0067] Of course, for those skilled in the art, other structures of the cover plate assembly and its working principles are understandable and achievable, and will not be described in detail in the present invention.

[0068] According to a second aspect of the present invention, there is provided an electronic device, such as Figure 1 and Figure 2 As shown, it includes the cover assembly in the above embodiment. Since the cover assembly according to the embodiment of the utility model has the above technical effects, the electronic device according to the embodiment of the utility model should also have the corresponding technical effects. That is, the electronic device of the utility model adopts the cover assembly, which does not affect the frame size of the screen, supports full-screen ambient light detection, can realize angle light collection, and can obtain the intensity of ambient light incident at different angles. And it realizes the brightness collection of light of different colors and different wavelengths. It can be used as a signal collection device to realize specific light control.

[0069] Of course, for those skilled in the art, other structures and working principles of the electronic device are understandable and achievable, and will not be described in detail in the present invention.

[0070] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
