What visual method is the best for observing LCD liquid crystal screens?

　　We usually use segment code LCD screens. I don't know if you have noticed it. For instance, have you noticed that some angles of the computers we use are 60 degrees? This is the direction we see

　　The viewing Angle, simply put, is the Angle at which the display pattern can be seen clearly. It is determined by the friction direction of the directional layer and cannot be changed by rotating the polarizer.

　　Most of the angles we usually see are frontal. Perspectives also have various names, and they are named after the hour of the hour hand, such as the 6:00 perspective, 12:00 perspective, and so on.

　　The 6:00 viewing Angle refers to the ideal LCD display effect in the area from the plane direction to the normal direction of the hour hand at 6 o 'clock. The 12:00 viewing Angle refers to the ideal display of the area from the plane to the normal direction of the hour hand at 12 o 'clock.

　　The viewing Angle of an LCD is determined by the position of the LCD display screen on the instrument. For instance, calculators are usually placed on a table or held in hand for use. It is best to make the LCD with a 6:00 viewing Angle.

　　Some LCD screens on instruments are installed below the line of sight of the human eye, usually designed with a 12:00 viewing Angle. The clock in a car is usually installed on the driver's right side, and it is best to set it at a 9:00 Angle.
