公开了具有能够执行多图像转换的改进结构的电子设备。 根据本发明的实施例的电子设备包括显示多个图像的显示装置。 显示装置包括：第一图像和第二图像，以选择性地彼此显示; 布置成与屏幕相邻的第一导光层; 第二导光层，其通过在其间具有第一导光层而布置成面对屏幕; 以及至少一个光源，其布置成选择性地照亮所述第一导光层或所述第二导光层，其中所述第二导光层的厚度比所述第一导光层的厚度大至少25％且至多45％ 导光层，使得从第二导光层接收的光源发射的光量大于从光源发射并由第一导光层接收的光量。

It discloses an electronic product having an improved structure is a multi-image (multi-image) to be converted. Electronic products between has a display device for displaying a plurality of images, wherein the display device is the first image and the second image, the first light guide layer disposed adjacent to the said screen, said first light guide layer that is selectively displayed in each other the place that is arranged to face the screen on the second light guide layer and the first light guide layer and the second light guide layer selectively to the light modulation, and includes at least one light source is disposed, it is emitted from the light source and the second in the amount of light entering the light guide layer is emitted from the light source of the first and the second light guide layer to greater than the amount of light entering the light guide layer has to have a thicker thickness than 45% or more 25% than the thickness of the first light guide layer It characterized.
