Open source development board Mixtile ( m too ) , external TFT adapter plate mounted on a 7-inch touch screen , accompanied by two acrylic (ACRYLIC) board as the device enclosure best odm tablet pc maker. This " tablet " is mainly run by Mixtile Android system output to the touch screen , touch-screen operation through the entire system operation.
The homemade " Tablet PC" is a major part of the domestic open source development board Mixtile ( m too ) , external adapter plate mounted on a TFT 7 inch touch screen , accompanied by two acrylic (ACRYLIC) board as the device housing ( we should not be too concerned about the whole thickness ) , on the formation of a support for multi-touch tablet.
In the design of the tablet front , designers have experimented connected display effect. Through this experiment , found Mixtile voltage and resolution are a problem to be solved .
Among the designer has used an old board to compose level shift circuit , and from this process of fly line design point of view , we can see that time in order to connect to Mixtile touch designers spent a lot of thought , and use a lot of small gimmick.
Designers worked in 5-inch and 7- inch screen on the touch-screen operation effects were tested , and the last to pass the test , the d! esigner found that as the system default output resolution is not compatible with the parameters of the screen , on the screen at a resolution smaller virtual keys will be lost ( this issue is not resolved , interested readers may visit mixtile.com participate in the discussion ) .
According fly line before finishing design a TFT adapter plate , the image above into the following wire circuit eventually finishing the entire PCB board .
