Detailed Description
Referring to fig. 1 to 5, a light emitting display structure includes a PCB 3 located at a bottom layer, a display panel box 2 located at a middle layer, and a display film 1 located at an upper layer. And a plastic part 7 on the display membrane 1.
The PCB 3 is provided with an LED lamp 4. In this embodiment, the LED lamp includes a first LED group 4-1 in the middle for displaying a number "88" (i.e., for displaying all integers from 00-99), a second LED group 4-2 on the left side of the first LED group for displaying a circle icon, and a third LED group 4-3 on the right side of the first LED group for displaying a circle icon.
The membrane 1 is provided with a pattern 1-1 to be displayed, comprising a '88' positioned in the middle, a seat ring pattern and a water drop shape respectively positioned at two sides. The pattern 1-1 can be various according to the requirement, and the LED lamp on the PCB board can be arranged at the corresponding position.
The display board box 2 comprises a through hole 4 of '88' in the middle, a first through hole 5 on the left side and a second through hole 6 on the right side.
Referring to fig. 4 and 5, taking the first through hole 5 as an example, the horizontal line L where the LED lamp is located is taken as a boundary, and the first through hole includes an upper portion and a lower portion, wherein the lower portion of the top surface of the LED is a lower half portion, and the upper portion of the top surface of the LED is an upper half portion. The area of the top surface of the upper half part is larger than that of the bottom surface of the lower half part, the upper half part is in an inverted frustum shape (the section is trapezoidal), the diameter of the upper top surface of the frustum is D1, the diameter of the lower bottom surface of the frustum is D2, and D1 is larger than D2. The ratio of the diameter of D2 to D1 ranged between 1.2 and 1.6. Preferably between 1.3 and 1.5. The acute angle between the inclined plane 5-1 of the frustum and the horizontal plane on which the top surface of the LED lamp is positioned is 50-80 degrees. Preferably 60-75 degrees.
Preferably, the height of the through-hole is 5mm to 8 mm.
The lower half part of the first through hole 5 is rectangular in section, and the top of the first through hole is the bottom of the funnel. The height H of the lower half part is the same as the height of the LED lamp. The side surface of the through hole is a smooth surface.
In the case of other patterns, such as the "88" shape, it is also desirable that the "88" via 4 have a top area greater than a bottom area by a ratio in the range of 1.2-1.6. Preferably between 1.3 and 1.5. The acute angle formed between the side edge of the bottom surface of the through hole 4 and the side edge of the top surface at the corresponding position in the vertical direction and the bottom surface or the top surface is 50-80 degrees.
The utility model discloses when the equipment, aim at each corresponding light trap of display panel box 2 with each LED lamp of PCB board, later, the upper surface of display panel box 2 covers with showing diaphragm 1. And finally covering the plastic part. Because the structure of the utility model is beneficial to clear display patterns, the display effect can be enhanced by about 30-40%. Therefore, ABS, HIPS, PP and other materials can be adopted as the plastic part. The reason for this may be that, as shown by the dotted line in fig. 4, the smooth surface of the side surface can emit and diffuse light many times, and if the top and bottom areas are uniform, the light emitted from the LED lamp is easily reflected back to the LED lamp by the display film.
