Supporting base and display device employing the same

A display device comprising:

• a supporting base comprising:
• a bottom plate having a plurality of side edges;
• and
• a plurality of stepwise supporting structures respectively connected with the side edges and raised up from the bottom plate, each stepwise supporting structure comprising a first raising segment, a first supporting segment, and a second raising segment, the first raising segment having a bottom end connected with one of the side edges of the bottom plate, the first supporting segment being substantially parallel to the bottom plate and extending outwards of the bottom plate from a top end of the first raising segment, the first supporting segment having an inner end connected with the top end of the first raising segment, the second raising segment being raised up from the first supporting segment and having a bottom end connected with an outer end of the supporting segment far away from the first raising segment, wherein if a thickness of the bottom plate is represented by D1, a thickness of the first supporting segment is represented by D2, a thickness of the first raising segment is represented by E1, and a thickness of the second raising segment is represented by E2, then the relationship between D1, D2, E1 and E2 is limited by E1<D1, E1<D2, and E2<D2, wherein the bottom plate and the stepwise supporting structures are made of a light reflective material, a thickness of the light reflective material is in positive correlation to a reflectivity of the light reflective material, and the reflectivity of at least one of the at least one supporting segment is greater than the reflectivity of at least one of the plurality of raising segments;
• a light guide plate disposed on the bottom plate;
• and
• a display panel disposed above the light guide plate.

A supporting base for a display device, the supporting base comprising:

• a bottom plate having a plurality of side edges;
• and
• a plurality of stepwise supporting structures connected with the side edges and raised up from the bottom plate, each stepwise supporting structure comprising a first raising segment, a first supporting segment, and a second raising segment, the first raising segment having a bottom end connected with one of the side edges of the bottom plate, the first supporting segment being substantially parallel to the bottom plate and extending outwards of the bottom plate from a top end of the first raising segment, the first supporting segment has an inner end connected with the top end of the first raising segment, the second raising segment being raised up from the first supporting segment and having a bottom end connected with an outer end of the first supporting segment far away from the first raising segment;
• wherein the bottom plate and the stepwise supporting structures are made of a light reflective material, a thickness of the light reflective material is in positive correlation to a reflectivity of the light reflective material, and the reflectivity of at least one of the at least one supporting segment is greater than the reflectivity of at least one of the plurality of raising segments;
• wherein if the reflectivity of the bottom plate is represented by R1, the reflectivity of the first supporting segment is represented by R2, the reflectivity of the first raising segment is represented by S1 and the reflectivity of the second raising segment is represented by S2, then the relationship between R1, R2, S1 and S2 is limited by S1<R1, S1<R2, and S2<R2.
