Description

Technical Field

[0001] This utility model relates to an electronic paper advertising carrier. Background Technology

[0002] Electronic paper advertising carriers are products that use electronic paper display layers to assist in displaying advertising information. To enhance the display effect, dynamic display areas are set on the electronic paper advertising carrier, and the electronic paper display layer alternates between displaying two colors with different brightness in the dynamic display area. However, when the external ambient temperature is low, the dynamic display area may frost or fog due to the drop in temperature, making the dynamic display of the electronic paper advertising carrier unobservable. Summary of the Invention

The heating layer includes a main heating area located in an opaque region and a transparent heat-conducting area located in a translucent region; and the transparent heat-conducting area is thermally connected to the main heating area.

[0004] Preferably, the main heating area of ​​the heating layer includes: an insulating heat-conducting layer superimposed on the opaque area of ​​the cover plate, and an electric heating wire built into the insulating heat-conducting layer.

[0005] Preferably, the insulating and thermally conductive layer of the main heating area is a thermally conductive silicone layer.

[0006] Preferably, the transparent heat-conducting area of ​​the heating layer includes: a transparent insulating heat-conducting layer superimposed on the light-transmitting area of ​​the cover plate; and the transparent insulating heat-conducting layer is thermally connected to the insulating heat-conducting layer of the main heating area.

[0007] Preferably, the transparent insulating thermally conductive layer of the transparent thermally conductive region is a transparent thermally conductive silicone layer.

[0008] Preferably, the cover plate has multiple light-transmitting areas, and the heating layer also has multiple transparent heat-conducting areas, with each of the multiple transparent heat-conducting areas corresponding to one of the multiple light-transmitting areas.

[0009] The advantages and beneficial effects of this utility model are as follows: it provides an electronic paper advertising carrier that enables the human eye to observe a dynamic display effect of alternating light and dark; and it can prevent the dynamic display area (i.e., the light-transmitting area of ​​the cover plate) from frosting or fogging due to the decrease in external ambient temperature, so that the electronic paper advertising carrier can be effectively observed. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the present invention. Detailed Implementation

[0011] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0012] The specific technical solution of this utility model is as follows: like Figure 1 As shown, this utility model provides an electronic paper advertising carrier, including: an electronic paper display layer 1, a cover plate 2 superimposed on the outer side of the electronic paper display layer 1, and a heating layer 3 superimposed on the outer side of the cover plate 2. The cover plate 2 includes a light-transmitting area 21 and an opaque area 22; the electronic paper display layer 1 can alternately display two colors with different brightness in the light-transmitting area 21 (such as alternating black and white). The heating layer 3 includes: a main heating region 31 located in the opaque region 22, and a transparent heat-conducting region 32 located in the light-transmitting region 21; and the transparent heat-conducting region 32 is thermally connected to the main heating region 31. The main heating area 31 of the heating layer 3 includes: an insulating and heat-conducting layer superimposed on the opaque area 22 of the cover plate 2, and an electric heating wire built into the insulating and heat-conducting layer; the insulating and heat-conducting layer of the main heating area 31 is a heat-conducting silicone layer. The transparent heat-conducting region 32 of the heating layer 3 includes: a transparent insulating heat-conducting layer superimposed on the light-transmitting region 21 of the cover plate 2; and the transparent insulating heat-conducting layer is thermally connected to the insulating heat-conducting layer of the main heating region 31; the transparent insulating heat-conducting layer of the transparent heat-conducting region 32 is a transparent heat-conducting silicone layer. The cover plate 2 has multiple light-transmitting areas 21, and the heating layer 3 also has multiple transparent heat-conducting areas 32, and each of the multiple transparent heat-conducting areas 32 corresponds to one of the multiple light-transmitting areas 21.

[0013] The working principle of this new electronic paper advertising carrier includes: External light can pass through the light-transmitting area 21 of the cover plate 2 and enter the electronic paper display layer 1. The incident light is reflected by the electronic paper display layer 1 and then passes through the light-transmitting area 21 of the cover plate 2 again, and is finally seen by the human eye. The electronic paper display layer 1 can alternately display two colors with different brightness in the light-transmitting area 21 (such as alternating black and white), which allows the human eye to observe the dynamic display effect of alternating brightness and darkness. Furthermore, when the external ambient temperature is low, the electric heating wire of the main heating area 31 of the heating layer 3 is energized and heated, causing the main heating area 31 of the heating layer 3 to heat up. Then, the insulating and thermally conductive layer (thermal conductive silicone layer) of the main heating area 31 conducts the heat to the transparent insulating and thermally conductive layer (transparent thermal conductive silicone layer) of the transparent thermally conductive area 32. In turn, the transparent insulating and thermally conductive layer (transparent thermal conductive silicone layer) of the transparent thermally conductive area 32 of the heating layer 3 heats the light-transmitting area 21 of the cover plate 2, which can prevent the light-transmitting area 21 of the cover plate 2 (i.e., the dynamic display area) from frosting or fogging due to the decrease in the external ambient temperature, so that the electronic paper advertising carrier can be effectively observed.

[0014] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
