Cholesteric liquid crystal is one kind of liquid crystal molecules. The pitch of cholesteric liquid crystals is about 300nm, which is on the same order as the wavelength of visible light. The pitch of the cholesteric liquid crystal is very sensitive to temperature and produces a strongly selective reflection when the pitch coincides with the wavelength of the light. The liquid crystal pitch changes with the rise of temperature, the color changes from orange red to green to blue purple in sequence, and the color is reversible when the temperature returns. And is thus a thermally sensitive liquid crystal. Can be made into thermosensitive liquid crystal paint to display temperature variation. And the temperature point and the temperature range of the color change can be adjusted in a self-defining way. It can be understood that the temperature point and the temperature range of the color change of the cholesteric liquid crystal of different types are different, and the user can select the type of the cholesteric liquid crystal according to the temperature point and the temperature range of the color change. It is understood that the different kinds of cholesteric liquid crystals have different pitches at the same temperature, i.e. the different kinds of cholesteric liquid crystals selectively reflect different wavelengths of light at the same temperature, so that the different kinds of cholesteric liquid crystals exhibit different colors at the same temperature.
As shown in fig. 3 and 4, in an embodiment, the heat-sensitive element 120 further includes an ink layer 124, and the ink layer 124 is printed on a side of the second protective layer 123 opposite to the cholesteric liquid crystal coating 122, so that the color of the cholesteric liquid crystal coating 122 is more obvious, and a user can observe the color of the cholesteric liquid crystal coating 122 more clearly, thereby determining the temperature of the casing 100.
As shown in fig. 1a, 1b and 2, in an embodiment, the case body 110 has a 3D structure and includes a flat plate portion 111 and a bent portion 112. The bent portion 112 extends from the periphery of the flat plate portion 111, and the display screen assembly 200 is mounted on the bent portion 112 and is opposite to the flat plate portion 111. The housing body 110 includes an outer surface facing the exterior of the electronic device 10 and an inner surface facing the interior of the electronic device 10, which are disposed opposite each other. The heat sensitive element 120 is fixed to the inner surface of the case body 110 and is located in the area of the flat plate portion 111.

The light transmittance of the area of the flat plate part 111 where the thermosensitive element 120 is arranged is not less than 60%, so that the thermosensitive element 120 can be exposed through the flat plate part 111, and a user can see the color of the cholesteric liquid crystal coating 122 through the shell body 110, thereby judging the approximate temperature of the shell body 110. In another embodiment, the shell body 110 may also be a transparent structure as a whole, and the light transmittance is not less than 60%. The material of the housing body 110 may be transparent plastic or glass. In another embodiment, the case body 110 may include only the flat plate portion 111 and not the bent portion 112, that is, the case body 110 is a flat plate structure, and the thermosensitive element 120 is fixed on the inner surface of the case body 110 and can be exposed through the case body 110. With casing 100 except decorating and the protection effect, the function of integrated temperature display can make casing 100 produce colorful change's effect on the one hand, and on the other hand can carry out the temperature suggestion through the color change when the temperature change. The heat-sensitive element 120 is fixed to the flat plate portion 111 of the case body 110, so that the heat-sensitive element 112 is closer to the electronic component 300 generating heat of the electronic device 10, and thus the temperature of the electronic device 10 can be represented more accurately.
It is to be understood that when the thermosensitive element 120 is fixed to the inner surface of the case body 110, the first shield layer 121 is not essential and may be omitted. The cholesteric liquid crystal may be directly applied to the inner surface of the case body 110 or the second protective layer 123 to form the cholesteric liquid crystal coating 122, and then the second protective layer 123 is fixed to the inner surface of the case 100, which may be understood as that the first protective layer 121 and the case body 110 are integrally formed, and the function of the first protective layer 121 is integrated on the case body 110, so that the first protective layer 121 may be omitted. Of course, the first shield 121 may be present, and the first shield 121 is fixed to the inner surface of the case body 110 after the thermosensitive element 120 is manufactured.

The 6 cholesteric liquid crystal coatings 122 are arranged in a manner of increasing or decreasing critical temperature. The 6 critical temperatures are respectively identified at the positions of the first protective layer 121 corresponding to the corresponding cholesteric liquid crystal coating 122.
