[0026] In order to make the technical scheme of the utility model more clear, the utility model will be further described in detail below in combination with the drawings and specific embodiments.

[0027] Embodiment 1

[0028] In combination with the drawings Figures 3-4 A slope bowl cup device capable of improving reliability and consistency of viewing angle is suitable for the case that there is a height difference between the user's line of sight and the display screen, and can also protect the device. In some common use scenarios of public display screens, the display screen is generally located at a high position, and the user is located at a low position and needs to look up to see the display screen. Therefore, the basic unit bowl cup device constituting the display screen is made into a slope, which can be more consistent with the user's line of sight. Meanwhile, the inclined bowl cup device can also protect the lamp beads and can avoid damage to the device caused by direct sunlight.

[0029] The display screen is composed of a plurality of bowl cup devices as basic components. The bowl cup device is composed of a base 10 and a side wall 11 located on the side of the base 10. The side wall 11 is arranged around the base 10, and the side wall 11 is arranged in alignment along the edge line of the side of the base 10. The side of the side wall 11 is aligned with the side of the base 10.

[0030] The base 10 is provided with three primary color lamp beads 14, which are arranged at the center position of the base 10.

[0031] The side wall 11 is arranged along the edge line of the base 10 and surrounds the periphery of the three primary color lamp beads 14. The side wall 11 is a closed structure, and a glue groove 15 is formed in the side wall 11 on the base 10. The glue groove 15 is filled with encapsulation glue, which is used to fix the three primary color lamp beads 14 and provide good protection for the three primary color lamp beads 14, improve light efficiency, weather resistance and heat resistance, insulation and heat conduction, waterproofness and sealing.

[0032] The upper and lower side walls 11 of the circumferentially arranged side wall 11 are of unequal length structure, and the upper side wall 11 is longer than the lower side wall structure. The connecting line between the inner side of the upper side wall 11 and the lower side wall 11 is a slope of 5-30 degrees. The slope angle is calculated according to the position difference between the display screen and the user. The inclination angle is changed according to the distance and height difference between the user and the display screen. Preferably, the glue surface formed by the glue and the audience line of sight are perpendicular.

[0033] The other two side walls 11 between the upper and lower sides are correspondingly arranged following the slope between the upper and lower side walls 11, so that the glue groove 15 formed by the side wall 11 is a slope groove. After filling the glue in the glue groove 15, the solidified glue also forms a slope between the upper and lower side walls 11.

[0034] At this time, the bowl cup mouth surface is an inclined surface, and the inclination angle is 5-30 degrees. The inclined surface is inclined downward.

[0035] The inclined surface is toward the audience, and the light normal is exactly coincident with the line of sight. In this direction, the light intensity and color consistency are the best, and the device normal is downward, avoiding light interference and mirror reflection caused by the direct light of the peripheral light on the device

[0036] The device is inclined downward, which is equivalent to installing a "sun hat" for the device. In this way, the direct sunlight can be avoided, and the "sun hat" of the device can block the wind and rain, protecting the device from the influence of external adverse environmental factors.

[0037] The base 10 is also provided with a hardware belt 12, which is used to power the three primary color lamp beads 14, and the hardware belt 12 is fixed in the glue groove 15 synchronously with the three primary color lamp beads 14 when filling the glue.

[0038] When making the bevel bowl cup:

[0039] I. Empty support production link: the hardware belt is not changed at all, and the lamp bead injection link only injects the cup mouth into high and low cup mouth; the main function of the hardware belt is electrical connection, providing a chip die bonding surface and lamp bead fixing foot.

[0040] II. Packaging link: the solid welding process in the packaging link is not changed at all, and the auxiliary tool does not need to be replaced at all; because the bowl cup mouth is an inclined surface, the point glue process needs to be slightly changed in the machine configuration to match the lamp bead glue surface. In the packaging link, the three primary colors, i.e. R / G / B colors, are mixed into different colors by adjusting the brightness ratio of the three primary colors, thereby displaying images. The main function of the packaging glue is to protect the LED chip, improve the light efficiency, weather resistance and heat resistance, insulation and heat conduction, waterproof and sealing. The shape of the bowl cup determines the light emitting angle and product quality.

[0041] III. Light screening link: although the lamp bead glue surface is an inclined surface, it has been baked and solidified. The suction nozzle of the light screening machine only needs to be designed into an inclined surface, and other changes are not required.

[0042] IV. Paste link: this link is similar to the light screening link, and only the suction nozzle needs to be designed into an inclined surface to match the lamp bead glue surface, and other changes are not required.

[0043] In some special cases, when the display screen needs to be used at a low position, the structure of the side wall 11 is reversed, and the side wall located at the lower side is longer than the side wall located at the upper side. At this time, the display screen located at the low position can still provide the best view for the user located at the high position.

[0044] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several deformations and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
