The viewing angle of a graphic lcd is the angle at which the display can be viewed without losing contrast or readability. Different graphic lcd modules have different viewing angles, such as 6:00, 12:00, 3:00 and 9:00 o’clock. You should choose a viewing angle that matches your project’s orientation and position.

Temperature range and Lighting conditions

If the LCD will be used in an outdoor setting with high temperatures and direct sunlight, it’s important to choose a display with high brightness and a wide temperature range to ensure reliable operation. On the other hand, if the LCD will be used in a low-light environment such as a medical device, a display with a high contrast ratio may be more appropriate. It’s important to carefully evaluate the requirements of the application and select a display that is well-suited to the specific environment in which it will be used.
