[0002] During normal driving, the A-pillar of the car will block the driver's view of the outside information. The A-pillar refers to the columnar structure on the left and right sides of the car's front windshield. Due to the safety performance requirements of the car, the A-pillar is generally designed to be thick and strong to provide corresponding protection for the occupants in the car. However, since the A-pillar area is large and close to the driver, it creates a large blind spot. There are currently some structural designs that can reduce the blind spot of the A-pillar, such as splitting an A-pillar into 2-3 columnar structures, but this design cannot effectively reduce or eliminate the A-pillar blind spot fundamentally. Every year, many traffic accidents are caused by the A-pillar blocking the driver's line of sight, especially the blocking on both sides when the car is turning. Summary of the invention

Figure 1 As shown, the automobile system according to the embodiment of the present invention includes: an information transmission device 100 , a display device 200 and a camera device 300 .

[0038] Taking the A-pillar on one side as an example, the camera device 300 is connected to the information transmission device 100 to obtain the media image of the road condition in the blind spot outside the A-pillar of the car, and send the media image to the information transmission device. The camera device 300 may preferably include a miniature infrared camera to ensure that clear media images can be obtained at night. Preferably, the camera device 300 is installed on the outside of the A-pillar to ensure that the media image of the blind spot can be fully obtained. In order to ensure that the media image of the blind spot can be fully obtained, a wide-angle camera and / or a combination of multiple cameras may be preferably used.

[0039] The information transmission device 100 is disposed inside a car, and receives the media image and sends the media image to the display device 200 .

[0040] Specifically, the display device 200 includes a plurality of LED display chips and a driving circuit arranged on a vehicle body, wherein the driving circuit includes a driving wire and a display driving chip, and the driving wire connects the display driving chip and the LED display chip.

[0041] Furthermore, the display driving chip is connected to the information transmission device 100 .

[0042] Preferably, Figure 2This is a structural schematic diagram of the automobile display system in Embodiment 1 of the present invention. As shown in the figure, the driving wire 210 includes a first wire 211 arranged along a first direction and a second wire 212 arranged along a second direction; the first wire 211 is connected to the first electrode of the LED display chip 220 and the display driving chip 230; the second wire is connected to the second electrode of the LED display chip 220 and is grounded; the display driving chip 230 is connected to the information transmission device 100 and the second wire.

[0043] Preferably, the first conductive wire 211 and the second conductive wire 212 are arranged in orthogonal directions and are insulated and isolated from each other.

[0044] Preferably, the first electrode is a positive electrode of the LED display chip 220 , and the second electrode is a negative electrode of the LED display chip 220 .

[0045] Furthermore, the display driver chip 230 can use an active drive mode or a passive drive mode to drive the LED display chip to display the media image. The embodiment of the present invention preferably uses a passive drive mode to drive the LED display chip.

[0046] Furthermore, the display device 200 in the embodiment of the present invention is arranged on the inner side of the A-pillar of the automobile or the inner surface of the front windshield of the automobile to synchronously display the road conditions of the blind spot outside the A-pillar.

[0047] In the first embodiment of the present invention, preferably, the display device 200 is arranged on the inner side of the A-pillar of the automobile as an example for explanation, and the display device 200 further includes a PI film (polyimide film) 240, and the driving wire is arranged on the PI film 240; the PI film 240 is wrapped and arranged on the inner surface of the A-pillar of the automobile. Specifically, the driving wire 20 can be formed on the PI film 240 by a printing process or a photolithography process. And the LED display chip 220 can be formed on the PI film 240 by a mass transfer process. Among them, the PI film is a flexible material, which can realize a better fit of the display device 200 to the A-pillar. The PI film is wrapped and covered at a set position on the A-pillar, preferably to achieve full coverage of the LED display chip on the inner surface of the A-pillar. In the alternative implementation, the display driver chip 230 is placed inside the vehicle body, and each of the first and second wires are connected respectively by leads. In this embodiment, by directly forming the driving wire on the PI film wrapped around the A-pillar, the display device can be better matched with the shape and curvature of different automobile A-pillars, enhancing the aesthetics and personalization.

[0048] Among them, the printing process can be an inkjet printing process or a screen printing process. Photolithography is a multi-step pattern transfer process.

[0049] Preferably, the information transmission device also includes a processing chip. When the information transmission device receives the media image, it can perform processing including but not limited to cropping and deformation on the media image, so that the display device arranged on the A-pillar can not only synchronously display the road conditions in the blind spot outside the A-pillar, but also realize the connection between the displayed media image screen and the road conditions and environment outside the vehicle observed by the driver. Based on the same principle, the display device 200 can also be arranged on the inner surface of the front windshield of the car.

[0050] In an alternative embodiment, the display device 200 is arranged on the inner surface of the front windshield of the car. Since the surface of the front windshield is flat, a glass substrate can be used instead of the PI film as a carrier of the driving wire and the LED display chip, and the glass substrate is arranged on the inner surface of the front windshield of the car. The working principle of the automobile display system of the embodiment of the present invention is specifically as follows: a media image of the blind spot road condition outside the A-pillar of the car is obtained by a camera device, the media image is received by an information transmission device, and the media image is sent to the display driver chip of the display device, the display driver chip processes the media image to generate a driving signal, and the driving signal is sent to the LED display chip through the driving wire, thereby driving the LED display chip to display the media image.

[0051] The technical solution of the embodiment of the present invention realizes that, under the premise of not affecting the normal driving action of the driver, the media image of the blind spot is obtained according to the camera device, and the display device is driven to display the media image according to the media image, so that the media image of the blind spot of the outer field of vision of the A-pillar can be observed without affecting the normal driving of the driver, which greatly avoids the obstruction of both sides during the turning process of the car and reduces traffic accidents.
