(2) refresh rate. Refresh rate refers to the display frame rate, ie, the frequencies of each pixel refresh time, it and the screen scanning speed and the ability to avoid screen flicker closely related. If the refresh rate is too low, the screen image may appear flicker or jitter.

(3) viewing angle. Viewing angle is standing on the center line of the screen up and down, left and right can still clearly see a certain position of the screen image angle range. In general, LCD viewing angles are symmetrical, but may not necessarily up and down, often up and down angle of less than about angles. Of course, viewing angle is the bigger the better.

(5) response time. Response time response of each pixel of the liquid crystal display response speed of the input signal, that is, from dark to light or light dimmer speed. The smaller the response time does not occur when watching motion picture film tail dragging feeling.
