Want to ask next LCD works, I know the LCD screen is made up of countless pixels, I want to ask is the LCD screen is a point by point scanning or progressive scan, for example, there is a 3 * 4 LCD screens, each line has three pixels, a total of four lines, which constitutes a complete 12 pixels of a picture, the twelve point is how to work, I think there are three kinds of
1. A chip control point a light, the first point is from the upper left corner, a point in a scan, know that the first line of all three points after scanning to the second line, this should call point by point scanning
2. The chip control the whole line, is a time t, chip control the whole line three pixel bright at the same time, this should call progressive-scan
3. The chip to control the entire LCD screen all pixels bright at the same time,
I think 3 is unlikely, so one and two exactly is what kind of work, I think the first one is horizontal frequency and field frequency, the second only field frequency
