Figure 3 and Figure 4 As shown, the display device 200 has a top side 201, a back side 202 and two opposite sides. The light shield 100 is suitable for being set downward along the opposite sides of the display device 200 until the lower ends of the side panels 12 and the fixing plate 14 are aligned with the lower end of the back side 202, and then the fixing plate 14 is adhered to the back side 202 using the adhesive layer S provided on the long side 142 and the short side 141, and the side panels 12 are adhered to the opposite sides of the display device 200 using the adhesive layer adjacent to the first fold line L1. Afterwards, the inverted plate 18 is attached to the side panels 12 connected thereto, the second connecting plate 26 is attached to the side panels 12 and the front panel 30 (indicated at Figure 7 ) is opposite to the display device 200.

[0042] Figure 5 This is a rear view schematic diagram of the application of the sunshade of the second embodiment of the utility model. Figure 6 This is a side view schematic diagram of the application of the light shield of the second embodiment of the utility model. Figure 7A schematic front view of the application of the light shield of the second embodiment of the utility model. Figure 5 As shown, the sunshade 100A further includes a light-emitting component 40, such as a light-emitting component containing a colorimetric lamp. When the user uses the sunshade 100A, the sunshade 100A can reduce excessive interference from light sources in the environment, and the light-emitting component 40 provides a stable and consistent lighting environment for the internal environment of the sunshade 100A. A colorimetric lamp with appropriate lighting parameters (such as color temperature, brightness, etc.) can be selected to allow the user to compare the image displayed on the display side with the physical object and reduce the error caused by color discrimination. Please also refer to Figure 5 and Figure 6 , the light emitting component 40 has two opposite ends and a plane P1. The two opposite ends of the light emitting component 40 are respectively assembled in the positioning holes 20 of the two side panels 12, and the position of the light emitting component 40 is fixed by the positioning piece 22, so that the light emitting component 40 is adjacent to the display side 203 of the display device 200, and the display side 203 is suitable for displaying images and is opposite to the back side 202. Further explanation, when the two opposite ends of the light emitting component 40 are inserted into the positioning holes 20, the reinforcing piece 24 is attached to the side panel 12 with the opening 241 corresponding to the positioning hole 20, and the positioning piece 22 is first bent outward along the sixth fold line L6, so that the plane P1 of the light emitting component 40 is pressed against the sixth fold line L6 and the limiting edge 246, and then the positioning piece 22 is attached to the plane P1 to enhance the structural stability of the light emitting component 40 and the surrounding of the positioning hole 20.

[0043] Continuing the above description, in order to provide a stable light source without causing glare when the light emitting component 40 illuminates the display side 203, the assembly position of the light emitting component 40 and the direction of the plane P1 are limited by the positioning hole 20 and the reinforcing sheet 24. Figure 4 , Figure 6 and Figure 7 When the sixth fold line L6 and the limiting edge 246 are respectively inclined relative to the first fold line L1 and the top edge 242, the positioning hole 20 and the reinforcing plate 24 can respectively use the sixth fold line L6 and the limiting edge 246 to make the plane P1 inclined relative to the top plate 10, and there is an inclination angle B between the plane P1 and the top plate 10, and the inclination angle B is greater than 0 degrees and less than 90 degrees; in one embodiment, the inclination angle B is between 10 degrees and 20 degrees, preferably 15 degrees; the portion of the plane P1 of the light-emitting component 40 located between the two side plates 12 is the light emitting portion P2, and the light beam C emitted through the light emitting portion P2 has a beam angle A, and the beam angle A is greater than or equal to 60 degrees and less than or equal to 160 degrees (60≦A≦160); in one embodiment, the beam angle A is between 80 degrees and 90 degrees, preferably 85 degrees. For example Figure 6As shown, the light-emitting component 40 has a shortest distance D from the display side 203. In order to avoid visual fatigue of the user due to the uneven brightness distribution of the light beam C irradiated on the display side 203 caused by the distance between the light-emitting component 40 and the display side 203 being too far or too close, the shortest distance D in this embodiment is between 2 cm and 6 cm, preferably 2.5 cm to 3 cm. The preferred value of the shortest distance D varies depending on the type of light-emitting component 40 selected, such as light-emitting components 40 of different brands or types (different types such as LED, OLED or Mini LED).

[0044] Figure 8 : is a schematic diagram of the application of the sunshade of the second embodiment of the utility model, wherein: Figure 8 The user U is, for example, a dental technician. Please also refer to Figures 6 to 8 The working area O of the display side 203 is the main image display area and color comparison and identification area when the user U operates the display device 200. In order to make the manufactured denture 50 meet the customer's requirements, such as color, the user U needs to compare and identify the color of the denture 50 and the tooth image 51 provided by the customer. Therefore, when the light emitting component 40 is assembled in the positioning hole 20, it has an inclination angle B and a shortest distance D, and emits a light beam C with a beam angle A. The illumination range of the light beam C includes the working area O, and the cross center E is the best illumination position.

[0045] Fig. 9 This is a three-dimensional schematic diagram of the application of the sunshade of the third embodiment of the utility model. Fig.10 1 is a top view schematic diagram of the application of the sunshade of the third embodiment of the utility model. Fig. 9 and Fig.10 As shown, the shade 100B includes a light emitting assembly 40 and a bracket 42. Both ends of the light emitting assembly 40 are respectively assembled in the positioning holes 20, wherein one end of the bracket 42 is inserted into the space Q (indicated at Figure 4 ) and connected to the light emitting assembly 40, and the other end of the bracket 42 is connected to the display device 200. The bracket 42 has a clamp 421 at one end connected to the light emitting assembly 40. The clamp 421 is, for example, a ring structure conforming to the shape of the light emitting assembly 40, suitable for clamping the light emitting assembly 40, but is not limited thereto.

[0046] The utility model adopts an integrated foldable structure design, so that the light shield is fixed with a glue layer (such as a traceless adhesive) to form a three-dimensional space when in use, and is stably pasted and mounted on the display device to reduce ambient light interference, provide a stable visual environment for the user, and make the display device suitable for various occasions; when not in use, the light shield can be easily disassembled without leaving residual glue, and can be flattened and stacked for easy storage; the light shield of the utility model is made of polypropylene material, and the characteristics of the material make the light shield tough, acid and alkali resistant, and high temperature resistant (140 to 170 degrees Celsius), which can improve the durability and applicability of the light shield. In addition, when the light shield including a light-emitting component (such as a light-emitting component containing a colorimetric lamp) is mounted on the display device, it can not only reduce ambient light interference, but also provide the user with the best stable light source when using the display device, improve the accuracy of color judgment, and reduce visual fatigue.
