4.3-inch split-screen display

Recently I have been tinkering with the left and right blind spot cameras of the car. The cameras have been installed and use a 4.3-inch folding display. The left and right signals need to be switched by the remote control, which is a bit troublesome. I added another display of the same size at the back, one for each side, but it is too unsightly to put it on the central control. I have been looking for a small screen display with two channels on the same screen. I searched online for a long time, and the smallest split screen is 7 inches, which is a bit too big. It would be nice if a 4.3-inch split screen can be used. Today I disassembled this 4.3-inch display. There is a small board inside, four input lines, red and black for the car ±12V, and yellow and white for the two-channel camera analog signals. Can you please tell me how to achieve the same screen display? ?

Is it okay to make a picture-in-picture or refer to the mobile phone? I am just giving my opinion for reference only.

Is there any possibility of downloading a terminal split screen software tool on the Internet?

This requires redesigning the screen's hardware and software. It's better to look for a screen that directly supports it. There's nothing you can do if you can't find one.

Just buy a ready-made product and don't bother yourself. You bought it too, so it's hard to support a function that wasn't there when it was designed.

On Taobao, a rearview mirror with a 4.3-inch dual-screen dual display and 4-channel video input is only more than 300 yuan.

I have learned about it, but the problem is that our car has a built-in driving recorder and a built-in rearview mirror.

I found a solution. I searched for a splitter on Taobao and it solved it.
