Patent ID: 8325106

Claim:
A seamless display apparatus, comprising: a backlight module, positioned at a bottom side of the seamless display apparatus, and adapted for emitting a light; a protective glass, positioned at a top side of the seamless display apparatus, the protective glass comprises an image-presenting region; at least a first panel and a second panel arranged side by side, the first panel and the second panel being positioned between the backlight module and the protective glass, wherein a region between the first panel and the second panel is an invisible region, wherein the image-presenting region is positioned projectively corresponding to the invisible region; and a light-pervious hollow tube, positioned over the invisible region between the first panel and the second panel, and under the protective glass, the light-pervious hollow tube comprising an inner vacant space, outer sidewalls, and inner sidewall, wherein the outer sidewalls and the inner sidewalls are adapted for twice refracting the light emitted from the backlight module for providing an outputting light outputted from the image-presenting region of the protective glass; wherein the light-pervious hollow tube is longitudinally disposed along a joint section between the first panel and the second panel and has an outer cross-section and an inner cross-section, wherein the outer cross-section of the light-pervious hollow tube is trapezoid shaped and has a first outer side, a second outer side, a third outer side which is a long side, and a fourth outer side which is a short side, and the inner cross-section of the light-pervious hollow tube is triangle shaped and has a first inner side, a second inner side, and a third inner side, and a first inner angle, wherein the first inner angle is defined as an included angle between the first inner side and the second inner side, wherein the third outer side is adjacent to a bottom of the protective glass, and the third outer side is parallel with the third inner side and the protective glass, and the fourth outer side and the first inner angle are collimated toward the invisible region between the first panel and the second panel.
