Please refer to FIG. 2 and FIG. 4. FIG. 4 is a section view of a display supporting unit in FIG. 1 in an embodiment. In an embodiment, the support arm 22 includes a housing 221 and a pivot structure 222. The housing 221 sleeves on the pivot structure 222 to cover interior components. The pivot structure 222 includes a center shaft 2221 and an outer sleeve 2222. The outer sleeve 2222 is sleeved on the center shaft 2221 and fixed to the base 21. The center shaft 2221 is capable of rotating relative to the outer sleeve 2222. As shown in FIG. 4, an annular protrusion 2223 is disposed in the interior of the outer sleeve 2222. An end of the shaft 2221 includes an annular neck portion 2224 corresponding to the annular protrusion 2223. The annular neck portion 2224 of the center shaft 2221 is disposed corresponding to the annular protrusion 2223 of the outer sleeve 2222 to fix the center shaft 2221 to the outer sleeve 2222. Thus, the center shaft 2221 is rotatable relative to the outer sleeve 2222.
The light emitting unit 23 is fixed to the center shaft 2221. The light cover 24 is fixed to the center shaft 2221. Thus, the light emitting unit 23 and the light cover 24 rotate simultaneously with the rotation of the center shaft 2221. In the embodiment, the light emitting unit 23 includes a circuit board 231, a lighting emitting diode 232 and a positioning member 233. The positioning member 233 is fixed to the center shaft 2221. The lighting emitting diode 232 is disposed on the circuit board 231. The circuit board 231 is connected to the positioning member 233. When the light emitting unit 23 is fixed to the center shaft 2221, the lighting emitting diode 232 faces the bottom of the support arm 22, that is, a direction towards the base 21. In the embodiment, the sectional area of the positioning member 233 is larger than the area surrounded by the annular protrusion 2223 of the outer sleeve 2222. When the outer sleeve 2222 is sleeved on the center shaft 2221, and the light emitting unit 23 is fixed to the center shaft 2221, the annular protrusion 2223 is held by the center shaft 2221 and the light emitting unit 23. Then, the center shaft 2221 and the light emitting unit 23 are rotatable relative to the outer sleeve 2222.
When the support arm 22 is assembled to the base 21, the end of the support arm 22 for disposing the light emitting unit 23 and the light cover 24 is sleeved on the base 21. Then, the body 211 of the base 21 and the outer sleeve 2222 of the support arm 22 are fixed via the two fixing members 213. As shown in FIG. 2 and FIG. 4, in the embodiment, the fixing member 213 is a screw. The fixing member 213 passes through the body 211 to fix the body 211 to the outer sleeve 2222. In such a way, the support arm 22 and the base 21 are fixed together. The center shaft 2221 of support arm 22 is capable of rotating relative to the outer sleeve 2222 (that is, relative to the base 21).
Please refer to FIG. 4 and FIG. 5. FIG. 5 is a schematic diagram showing a projecting image of the display device in FIG. 1 onto a tabletop in an embodiment. In the embodiment, the light emitting unit 23 faces to the base 21. The light emitted from the light emitting unit 23 comes out from the bottom of the base 21. That is, the light is projected out through the light cover 24 and the translucent sheet 214. The body 211 is spaced apart from the tabletop 200a by a predetermined distanced via the three stands 212. The light emitted from the light emitting unit 23 is projected onto the tabletop 200a after the light passes through the light cover 24 and the translucent sheet 214. When the display unit 10 is in use and supported by the display supporting unit 20, the light from the light emitting unit 23 is projected onto the tabletop 200 through the light cover 24 and the translucent sheet 214. Whether the display unit 10 is powered or connected to the power supply is determined intuitively via the projection onto the tabletop 200.
In the embodiment, a first pattern 241 is formed on the light cover 24, and a second pattern 2141 is formed on the translucent sheet 214. After the light transmits through the light cover 24 and the translucent sheet 214 to the tabletop 200, the first pattern 241 and the second pattern 2141 are overlaid to be projected onto the tabletop 200 to form a pattern, as shown in FIG. 5. The pattern projected onto the tabletop 200 is various by forming different patterns on the light cover 24 and the translucent sheet 214, respectively.
In the embodiment, the second pattern 2141 is an annular pattern which is equally divided into three parts. The dividing line between two adjacent parts corresponds to the position of one of the stands 212. When the light cover 24 rotates along with the support arm 22, the first pattern 241 formed on the light cover 24 also rotates while the second pattern 2141 formed on the translucent sheet 214 of the base 21 is fixed. Therefore, the relative position relationship between the display unit 10 and the stands 212 is determined intuitively from the relative position relationship between the first pattern 241 and the second pattern 2141.
In the embodiment, the base 21 includes three openings 2112. The light emitted from the light emitting unit 23 passes through the three openings 2112 and then is projected onto the tabletop 200 to form a pattern of the three openings 2112. In an embodiment, to form other patterns onto the tabletop 200, the three openings 2112 are formed in the shapes correspondingly. In the embodiment, the openings 2112 are formed corresponding to the positions of the stands 212, respectively. Consequently, upon the projection onto the tabletop 200, the relative position between the display unit 10 and the stands 212 is determined intuitively. In an embodiment, with the light cover 24, the translucent sheet 214 and the openings 2112, a multi-level pattern radiating out from the center is provided.
