[0029] As shown in FIG1 to FIG4 , an embodiment of the present application provides an electronic device, the electronic device including a display structure 10 and an image sensor chip 20 . The display structure 10 includes: a substrate layer 11 and a display panel layer 12 that are stacked, and the display structure 10 also includes a display chip 13 .
[0030] Among them, the display panel layer 12 and the display chip 13 are located on the same side of the substrate layer 11, the image sensor chip 20 uses the substrate layer 11 as the chip base, and the image sensor chip 20 and the display chip 13 are located on different sides of the substrate layer 11. The image sensor chip 20 and the display chip 13 are connected through a signal line 30, and the signal line 30 is used to transmit image information between the image sensor chip 20 and the display chip 13.
[0031] It should be noted that the image sensor chip 20 and the display chip 13 are directly connected via a signal line 30 .
[0032] The display chip 13 may use the substrate layer 11 as a chip base.
[0033] The signal line 30 may be provided through the substrate layer 11 . Specifically, a via hole 111 may be provided on the substrate layer 11 . The signal line 30 passes through the via hole 111 to connect the image sensor chip 20 and the display chip 13 .
[0034] The image sensor chip 20 is connected to the display chip 13 via a signal line 30 . One end of the signal line 30 may be connected to the image sensor chip 20 , and the other end of the signal line 30 may be connected to the display chip 13 .
[0035] In one embodiment, as shown in Figures 2 to 4, the image sensor chip 20 includes an image sensor core module, an image signal processing (ISP) module, and an image interface module, and the display chip 13 includes a display digital-to-analog conversion module, a display numerical control module, and a display interface module. Any one of the image sensor core module, the image signal processing module, and the image interface module is connected to any one of the display digital-to-analog conversion module, the display numerical control module, and the display interface module via a signal line 30.
[0036] It should be noted that the image sensor chip 20 and the display structure 10 may share the substrate layer 11 , that is, the substrate layer 11 serves as both the base of the image sensor chip 20 and the base of the display structure 10 .
[0037] The image sensor chip 20 may be a complementary metal oxide semiconductor image sensor (CMOS image sensor, CIS) chip for a camera, or other types of image sensor chips, which are not limited in this embodiment. The image sensor chip 20 may also be described as a camera chip.
[0038] The display structure 10 may be an OLED display structure or a LED display screen structure.
[0039] It should be noted that the image sensor chip 20 and the display structure 10 share the substrate layer 11 , thereby enabling an integrated design of the image sensor chip 20 and the display structure 10 .
[0040] It should be noted that a signal compatibility module can be added to the display structure 10 or the image sensor chip 20 to solve the signal timing or compatibility problems that may be introduced by direct transmission of image signals between different modules, thereby achieving high-speed and delay-free video recording and transmission.
[0041] It should be noted that the image sensor chip 20 and the display structure 10 are directly fabricated on both sides of the substrate layer, leaving more space for arranging various compatible processing modules, thereby increasing the transmission speed.
[0042] It should be noted that a hole can be directly opened on the substrate layer (such as silicon base) at the bottom of the image sensor chip 20, and the signal line 30 passes through the hole. The image signal is directly transmitted to the position of the corresponding module of the display chip 13 through the signal line 30, realizing high-speed connection signal transmission.
[0043] As shown in FIG1 , the electronic device may further include a flexible printed circuit (FPC) 40 and a connector 50 for connecting to a main control chip. The main control chip may be a system on chip (SOC) chip. The SOC chip may be the main control chip of a mobile phone or a mixed reality (MR) device, such as a Qualcomm 888 chip or a MediaTek DX-1 chip.
[0044] It should be noted that virtual reality (VR), also known as virtual reality or virtual reality technology, is a brand-new practical technology developed in the 20th century. VR technology encompasses computer, electronic information, and simulation technologies. Its fundamental implementation is primarily computer-based, utilizing and integrating the latest advances in high-tech technologies such as 3D graphics, multimedia, simulation, display, and servo technology. Using computers and other devices, it creates a realistic 3D virtual world with multiple sensory experiences, including visual, tactile, and olfactory experiences. This creates an immersive experience for those in the virtual world. With the continuous development of social productivity and science and technology, the demand for VR technology is growing rapidly across all industries. VR technology has also made significant progress and is gradually becoming a new field of science and technology.
[0045] MR is a further development of virtual reality. By introducing real-world scene information into a virtual environment, this technology establishes an interactive feedback loop between the virtual and real worlds and the user, enhancing the realism of the user experience. Mixed reality is a combination of technologies that not only offers new viewing methods but also new input methods. These methods, when combined, drive innovation.
[0046] In related technologies, to implement MR technology, as shown in Figures 5 and 6, MR devices require multiple cameras and displays. The cameras capture real-world images, transmit them to a main control chip, and then transmit them from the main control chip to the MR display. This transmission process takes time and introduces a certain amount of latency, resulting in a poor user experience. Furthermore, the large number of cameras increases costs.
[0047] The embodiment of the present application provides a signal transmission method for a display camera module that integrates a display and a camera. The method combines the camera's complementary metal oxide semiconductor image sensor (CMOS image sensor, CIS) chip with a silicon-based organic light-emitting diode (OLED) or light-emitting diode (LED) display screen. The image signal captured by the camera is directly transmitted to the internal module of the display chip for processing and display, skipping the main control chip. This improves the transmission and display speed, achieves the lowest latency, and realizes synchronization between the MR device and the outside world. In addition, in terms of physical transmission, the camera and the display structure 10 share a wafer chip. The CIS of the shared camera has a larger area, wider accuracy and range, which can reduce the number of cameras and the number of wafers, thereby reducing costs.

The image sensor chip 20 and the display chip 13 are connected via a signal line 30, which is used to transmit image information between the image sensor chip 20 and the display chip 13. Thus, image information is directly transmitted via the signal line 30 between the image sensor chip 20 and the display chip 13, without having to pass through a main control chip, thereby reducing transmission time and display latency.

This embodiment does not limit the specific implementation of the connection between the image sensor chip 20 and the display chip 13 through the signal line 30.
[0056] The display value control module may include a random access memory (RAM) submodule. The display interface module may include a MIPI submodule, which is an interface module for the display chip 13. The RAM submodule is a fast storage and random access memory module. The display digital-to-analog conversion module is a module that converts digital signals into analog signals.

[0062] In addition, the image signal processing module can be in communication connection with the main control chip, and the main control chip outputs an enable signal (ES) to control the image signal processing module to transmit image information to the display value control module.
[0063] It should be noted that the display digital-to-analog conversion module outputs a source signal to the display panel for display.
[0064] In one embodiment, the captured image signal, after passing through the ISP, is directly transmitted from the image sensor chip 20 to the numerical control module RAM storage module of the display chip 13 for direct display. The main control chip can be enabled in real-time transmission mode, in which case the main control chip will not transmit to the display chip 13. The main control chip can also add an ES output control ISP module to directly transmit the signal to the display numerical control module. The camera can also simultaneously transmit image information to the main control chip, which stores it, but does not output it to the display chip 13.

[0069] Among them, the image array submodule in the image sensor core module collects image information, processes the collected image information through the ADC submodule, and transmits it to the display digital-to-analog conversion module through signal line 30. The display digital-to-analog conversion module transmits the image information output by the ADC submodule to the display panel for display.
[0070] In addition, the image sensor core module may be in communication connection with a main control chip, and the main control chip outputs an enable signal to control the image sensor core module to transmit image information to the display digital-to-analog conversion module.
[0071] In one embodiment, the ADC module of the image sensor chip 20 transmits image signals to the DAC module of the display chip 13.

The main control chip can also add an ES output control ADC module to directly transmit signals to the display DAC module. The camera can also simultaneously transmit image information to the main control chip, which stores it, but does not output it to the display chip 13.

[0091] In related technologies, the signal transmission method within MR devices is: camera analog signal > analog-to-digital conversion > digital signal > MIPI transmission to the SOC, which stores and sends it to the display > MIPI > display IC > digital signal processing > digital-to-analog conversion > analog signal output to the display, which then displays the image. When using MR devices to talk or meet with people, signal transmission time causes a delay, resulting in a delay between the image seen in MR and the real world, affecting the user's MR experience.
[0092] The present invention provides a signal transmission method that enhances real-time MR transmission, enabling fast and minimally delayed signal transmission. The backside of a silicon-based display screen serves as the substrate for a camera chip, with the display structure 10 and the camera sharing a single silicon-based wafer.

The camera signal can be directly transmitted to the display panel for display via a signal line 30 passing through a silicon-based via.
[0095] In addition, the image sensor chip 20 and display structure 10 in the electronic device of the present invention can share a connector to transmit data to the CPU of the MR device. The display chip 13 and the display pixel driver circuit of the display screen can both be arranged on a silicon-based wafer, rather than as a separate display IC.
[0096] For example, as shown in FIG7 , from bottom to top, the image sensor chip 20 may include: a substrate layer 11 (bulk silicon), metal leads, a photodiode, a filter array, and a microlens.
[0097] In addition, the display panel layer may include: an anode electrode, an organic electro-luminescence (EL) layer, a cathode electrode, a protective film, an on-chip color filter (OCCF), a microlens, a resin layer, and a glass cover.
[0098] For example, as shown in FIG8 , from bottom to top, the display structure 10 may include: a substrate layer 11 (such as a silicon substrate), an anode electrode, an organic EL layer, a cathode electrode, a protective film, an OCCF, a microlens, a resin layer and a glass cover, etc.
[0099] For example, as shown in FIG9 , the image sensor chip 20 performs image capture, and the human eye views the image captured by the image sensor chip 20 through the display structure 10 .
[0100] Through the embodiments of the present application, a display screen and camera integrated module can be realized, which reduces the delay from MR imaging to display, improves the user's MR usage experience through low-latency real-time transmission, and reduces costs by reducing the number of wafers.
[0101] It should be noted that the electronic device of the embodiment of the present application can be used not only by MR devices, but also by all devices that require low latency, such as devices used for real-time camera and display during driving of a car.
[0102] As shown in FIG10 , an embodiment of the present application further provides a display control method, which is applied to the electronic device described in the embodiment of the present application. The method includes:
[0103] Step 101: Acquire image information through the image sensor chip 20;
[0104] Step 102: Transmit the image information to the display structure 10 via the signal line 30 for display.
[0105] In the embodiment of the present application, image information is acquired by the image sensor chip 20 and transmitted to the display structure 10 for display via the signal line 30. Direct transmission of image information via the signal line 30 between the image sensor chip 20 and the display structure 10 eliminates the need for transmission via the main control chip, thereby reducing transmission time and display latency.
