Digital photo frames first appeared in the United States around the beginning of this century. The English name is Digital Photo Frame or Digital Picture Frame, or DPF for short, alias digital photo frame, digital photo frame, electronic photo frame, etc. I don't know if you have noticed, digital photo frames appear frequently in every movie "Harry Potter". Compared with the traditional glass photo frame, the digital photo frame makes the photos in the frame move, beyond the imagination of human beings for thousands of years. Digital photo frames are a great breakthrough in imaging technology and a benefit brought to us by the digital age.

In terms of medium-sized digital photo frames, since cost is the most important consideration for manufacturers, TopView is used for white LEDs, and the thickness requirements are not as strict as mobile phone backlights. Because of the packaging method of Topview, the performance in terms of brightness and lifespan is better than that of Sideview, and the cost of packaging materials of TopView is lower and the yield is higher, so that the overall cost can be reduced.
