[0016] Figure 1 A block diagram of a transport device according to an embodiment of the present disclosure is shown. Figure 1The transport device 100 includes a head end 110. The display system 200 is used in the transport device 100. The display system 200 is electrically connected to the head end 110 via a bus line 120. The transport device 100 is a vehicle capable of carrying people, including a vehicle, an airplane, or a ship. Taking a vehicle as an example, the bus line 120 is, for example, a vehicle bus of a controller area network (CAN).

[0017] Figure 2 Show Figure 1 A block diagram of a display system of an embodiment. Please refer to Figure 2 The display system 200 includes a display 210 , a plurality of first sensor components 220_1 , 220_2 , 220_3 , 220_4 , and a system chip 230 .

[0018] The display 210 includes a liquid crystal display, a light emitting diode display or an organic light emitting diode display. The first sensor components 220_1, 220_2, 220_3, 220_4 are used to provide a plurality of detection signals S1 to the system chip 230. The first sensor components 220_1, 220_2, 220_3, 220_4 are sensor components of the same type, for example, infrared sensors or charge coupled devices (CCD). The number and type of the first sensor components are not limited to the present disclosure.

[0019] The system chip 230 is electrically connected to the display 210 and the first sensor components 220_1, 220_2, 220_3, and 220_4. The first transmission interface IF1 includes, for example, a Mobile Industry Processor Interface (MIPI), an Ethernet interface, or a Wireless Fidelity (Wi-Fi) interface. The system chip 230 is electrically connected to the head end 110 via a second transmission interface IF2. The second transmission interface IF2 includes, for example, a CAN interface.

[0020] The system chip 230 includes an image processor circuit 232, a central processing unit circuit 234, and a timing controller circuit 236. The image processor circuit 232 is electrically connected to the first sensor components 220_1, 220_2, 220_3, and 220_4 through a first transmission interface IF1. The central processing unit circuit 234 is electrically connected to the image processor circuit 232. The central processing unit circuit 234 is electrically connected to the head end 110 through a second transmission interface IF2. The timing controller circuit 236 is electrically connected to the central processing unit circuit 234. The image processor circuit 232 is used to analyze the detection signal S1 provided by the first sensor components 220_1, 220_2, 220_3, and 220_4, and output the analyzed detection signal S1 to the central processing unit circuit 234. The central processing unit circuit 234 is used to generate an integration instruction S2 according to the analyzed detection signal S1, and give the integration instruction S2 to the timing controller circuit 236. The integration instruction S2 includes the image content to be displayed on the display 210 and optimized by the image processor circuit 232. The timing controller circuit 236 is used to drive the display 210 to display images according to the integrated instruction S2.

[0021] The integrated instruction S2 is provided to both the timing controller circuit 236 and the head end 110. For example, the CPU circuit 234 outputs the integrated instruction S2 to the head end 110 via the second transmission interface IF2. The head end 110 can control the transport device 100 to perform corresponding actions according to the integrated instruction S2.

[0022] In this embodiment, the image processor circuit 232, the central processing unit circuit 234 and the timing controller circuit 236 may include a controller or a processor, which is a circuit component with computing capabilities. Alternatively, the controller or processor included in the processor circuit can be designed by hardware description languages ​​(HDL) or any other design method for digital circuits familiar to those skilled in the art, and can be a hardware circuit implemented by a field programmable gate array (FPGA), a complex programmable logic device (CPLD) or an application-specific integrated circuit (ASIC). The image processor circuit 232 can also be an image processing module, which is implemented as a plurality of program codes. These program codes will be stored in the memory, and these program codes will be executed by a circuit component with computing capabilities to perform the corresponding image processing operations. The present disclosure does not limit the implementation of each circuit module in the system chip 230 by software or hardware.

[0023] Figure 3 A block diagram of a display system according to an embodiment of the present disclosure is shown. Figure 3 The display system 300 further includes a third sensor component 250, and the system chip 230 further includes a local dimming circuit 238. The display 210 includes a display panel 212 and a light source module 214. The third sensor component 250 is electrically connected to the system chip 230. The local dimming circuit 238 is electrically connected to the central processing unit circuit 234.

[0024] Specifically, the third sensor component 250 is electrically connected to the CPU circuit 234 via the third transmission interface IF3. The third transmission interface IF3 is, for example, an Inter-Integrated Circuit (I2C) interface. The third sensor component 250 is, for example, an ambient light sensor for providing an ambient light signal S3. The number and type of the third sensor components are not intended to limit the present disclosure.

[0025] The head end 110 generates a first image signal S4 according to the integrated instruction S2. The first image signal S4 is provided to the central processing unit circuit 234 through the second transmission interface IF2. For example, when the head end 110 is to perform a safety warning through the display 210, the first image signal S4 can be provided to the central processing unit circuit 234. The central processing unit circuit 234 then drives the timing controller circuit 236 and the local dimming circuit 238 according to the first image signal S4. The timing controller circuit 236 provides the second image signal S5 to the display panel 212 to drive the display panel 212 to display an image screen. The image screen includes a safety warning. The local dimming circuit 238 provides a third image signal S6 to the light source module 214 to control the light source module 214 to perform a local dimming function.

[0026] Figure 4 Show Figure 3 Flow chart of the operating method of the display system of the embodiment. Please refer to Figure 3 and Figure 4 , taking vehicles as an example, Figure 3 The display system 300 of the embodiment is, for example, an electronic device used in a vehicle cockpit system. Therefore, the display system 300 includes a vehicle display, which can receive data signals and image signals from devices such as a vehicle computer or an electronic control unit (ECU) to display dashboard information and image information respectively, but the present disclosure is not limited to receiving signals from a vehicle computer and an electronic control unit.

[0027] The first sensor components 220_1, 220_2, and 220_3 are, for example, arranged at the front seat of the vehicle, and the first sensor component 220_4 is, for example, arranged at the rear seat of the vehicle. The image processor circuit 232 may select the detection signal S1 for analysis according to the actual situation in the vehicle. For example, the first sensor components 220_1, 220_2, 220_3, and 220_4 may first perform a preliminary scan. If the central processing unit circuit 234 determines that there is no one in the rear seat, the image processor circuit 232 may select the detection signal S1 of the three first sensor components 220_1, 220_2, and 220_3 of the front seat for analysis. In other words, the image processor circuit 232 analyzes the detection signal S1 provided by the first sensor components 220_1, 220_2, and 220_3 of the front seat, but does not analyze the detection signal S1 provided by the first sensor component 220_4 of the rear seat. In addition, the central processing unit circuit 234 may also determine whether there is someone in the rear seat according to whether the door of the rear seat has been opened first or the time when it was opened. In another embodiment, the selection of the first sensor components 220_1, 220_2, 220_3, 220_4 may also be determined by the driver through a vehicle interface, which may include a mobile phone application or a vehicle control panel.

[0028] Therefore, in step S100, the image processor circuit 232 selects, for example, the detection signal S1 provided by the first sensor components 220_1, 220_2, and 220_3 for analysis. Next, in step S110, the image processor circuit 232 analyzes the detection signal S1 provided by the first sensor components 220_1, 220_2, and 220_3, for example, analyzing the image content of the detection signal S1 to determine in real time whether the driver or the passenger has violated the rules. The image processor circuit 232 may also perform conventional image processing operations on the image content of the detection signal S1, for example, optimizing image characteristics such as image resolution and image brightness to improve the image display quality of the display 210. The image processor circuit 232 provides the image processing result (i.e., the analyzed detection signal S1) to the central processing unit circuit 234.

[0029] In step S120, the CPU circuit 234 generates an integrated instruction S2 according to the analyzed detection signal S1, and provides the integrated instruction S2 to the head end 110. For example, the CPU circuit 234 can provide a flag related to the driver monitoring system (DMS) to the head end 110, informing the head end 110 whether the driver or the passenger has violated the rules, and the head end 110 issues a safety warning. In other words, the CPU circuit 234 does not need to provide a large amount of image data to the head end 110, and the head end 110 does not need to perform image processing operations. According to the integrated instruction S2 (including the DMS flag) provided by the CPU circuit 234, the head end 110 can know whether the driver or the passenger has violated the rules, and thus issue a safety warning. In this way, the bandwidth of the image data transmitted by the CPU circuit 234 to the head end 110 can be greatly reduced. The violations include dozing off, turning the head, the person is not in the seat, or letting go of the steering wheel.

[0030] In addition, since the integrated instruction S2 includes the image processing result, the CPU circuit 234 also provides the integrated instruction S2 to the timing controller circuit 236 and the local dimming circuit 238, so that the timing controller circuit 236 and the local dimming circuit 238 can respectively perform the image driving function and the local dimming function.

[0031] In step S130, the headend 110 performs a safety warning according to the integrated instruction S2. The safety warning information includes controlling the vehicle to display a warning, automatic braking, sound warning, or display outside the vehicle. Alternatively, the safety warning includes notifying a specific mobile phone that the vehicle may be driving dangerously. Alternatively, the safety warning includes notifying the Global Positioning System (GPS) of the location of the accident.

[0032] In step S140, the third sensor component 250 can detect the intensity of the ambient light and provide an ambient light signal S3 to the central processing unit circuit 234. The central processing unit circuit 234 adjusts the brightness of the display 210 according to the ambient light signal S3, or adjusts the parameters of the first sensor components 220_1, 220_2, 220_3, 220_4, so that the first sensor components 220_1, 220_2, 220_3, 220_4 can provide good detection results.

[0033] Figure 5 A block diagram of a display system according to another embodiment of the present disclosure is shown. Figure 5, the display system 400 also includes a second sensor component 240. The second sensor component 240 is electrically connected to the system chip 230. Specifically, the second sensor component 240 is electrically connected to the image processor circuit through the first transmission interface IF1. The first sensor components 220_1, 220_2, 220_3 and the second sensor component 240 are different types of sensor components. For example, the first sensor components 220_1, 220_2, 220_3 are infrared sensors or CCDs, and the second sensor component 240 is a structured light sensor. The number and type of the first sensor components and the second sensor components are not intended to limit the present disclosure.

[0034] Figure 6 Show Figure 5 Flow chart of the operating method of the display system of the embodiment. Please refer to Figure 5 and Figure 6 In this embodiment, the image processor circuit 232 first selects the data provided by the second sensor component 240 for analysis (step S200), and then selects the data provided by the first sensor components 220_1, 220_2, and 220_3 for analysis (step S100). In step S200, the image processor circuit 232 analyzes the detection signal S1 provided by the second sensor component 240 to perform facial recognition on the driver.

[0035] In step S210, if the CPU circuit 234 determines that the driver has not passed the facial recognition, the method flow will enter step S220. In step S220, the head end 110 may notify the vehicle owner through the mobile phone that the vehicle may be stolen, or notify the vehicle owner of the current location of the vehicle through the Global Positioning System (GPS). In step S210, if the CPU circuit 234 determines that the driver has passed the facial recognition, the method flow will enter step S230. In step S230, the head end 110 may allow the driver to start the vehicle.

[0036] In step S210, if the CPU circuit 234 determines that the driver has not passed the facial recognition, the method flow will enter step S220. In step S220, the head end 110 can notify the vehicle owner through the mobile phone that the vehicle may be stolen, or notify the vehicle owner of the current location of the vehicle through the Global Positioning System (GPS). In step S210, if the CPU circuit 234 determines that the driver has passed the facial recognition, the method flow will enter step S230. In step S230, the head end 110 can allow the driver to start the vehicle.

[0037] In step S240, the central processing unit circuit 234 adjusts the brightness of the display 210 according to the ambient light signal S3, or adjusts the parameters of the first sensor components 220_1, 220_2, 220_3 and the second sensor component 240, so that the first sensor components 220_1, 220_2, 220_3 and the second sensor component 240 can provide good detection results. In step S210, if the central processing unit circuit 234 determines that the driver has not passed the face recognition, the method flow can also choose to enter step S240. In step S240, the central processing unit circuit 234 adjusts the parameters of the second sensor component 240 according to the ambient light signal S3 to perform the face recognition operation on the driver again.

[0038] In summary, in the embodiments of the present disclosure, the sensor assembly can be arranged in the display, and a system chip is arranged on the main board. The system chip integrates image processing function, display driving function and regional dimming function. The system chip can analyze the image in real time, and immediately inform the head end for processing when a violation is found, thereby reducing the data transmission bandwidth between the system chip and the head end.
