7 inch tft lcd display
The most common kinds of spacers used in TFT LCDs are bead (spherical) and column (patterned by lithography) type spacers. The collapse strength, recovery rate and height uniformity of those spacers play a major role in keeping the gap stable and, thus, the panel in good condition.Strong spacers will keep the gap in good shape even under severe outside impact, while higher recovery rate means less permanent damage from those impacts. On the other hand, better height homogeneity of spacers will lead to faster response time, wider viewing angle, higher resolution and contrast ratio of the display. It is therefore important to monitor and control those parameters when manufacturing LCDs.

How to Use LCD Projectors in Education?
Present class notes and materials using the LCD projector, just as you would have using an older device, such as a transparency projector. Connect the LCD projector to your laptop or desktop computer and open up the program that contains the presentation you'd like to give.Use the LCD projector to show picture slide shows. Hook the projector up to your computer and play a slide show of images from your Pictures folder while you narrate the images in the context of the class.Allow students to use this for their own class presentations and group activities. In the past, different groups of students may have experienced lesser or greater advantages completing in-class activities based on their ability to purchase more engaging materials for use in presentations and displays. Having technology such as the levels the proverbial playing field and allows students from all backgrounds to benefit equally.
