The invention relates to a digital picture frame, which comprises a display unit and a driving circuit board. The driving circuit board comprises a backlight driving circuit, a first storage unit, a main control chip and a time sequence controller. The backlight driving circuit provides working voltage for the backlight source of the display unit. The first storage unit is used for storing static pictures, dynamic images and frequency datum. The main control chip processes the static pictures, dynamic images and frequency datum stored by the first storage unit so as to acquire the graph data signal which is suitable for displaying by the display unit and the audio frequency signal for broadcasting by the digital picture frame. The time sequence controller controls and outputs the graph data signal output by the main control chip to the display unit according to time sequence so that the display unit displays the static pictures or dynamic images. The digital picture frame has the advantages of multiple functions and simple circuit structure.
Description
Technical field [0001] The invention relates to a digital photo display (Digital Photo Display). Background technique [0002] Digital cameras are widely loved by users because they are easy to use and can use the digital camera itself or a computer to realize the viewing function of digital photos. However, digital photos are stored on a memory card, CD or computer, and cannot be viewed directly. Therefore, the industry has developed a digital photo frame that allows users to store, display, and share digital photos with print quality through a digital photo frame that looks like a photo frame. [0003] Please refer to figure 1 And Figure 2, figure 1 It is a schematic diagram of the three-dimensional structure of a digital photo frame in the prior art. Figure 2 is figure 1 The exploded schematic diagram of the digital photo frame shown. The digital photo frame 10 includes a front frame 11, a display unit 12, a first drive circuit board 13, a second drive circuit board 14, a thir...
