The compounded coating or ink containing the thermoluminescent material is adopted in the modes of spraying, silk-screen printing, pad printing and the like, the process is simple, and the formed coating has good stability. By adopting a gluing process, the thermoluminescent material can be directly mixed with glue and coated on a panel to form a stable layer. The thermoluminescent material meeting the requirement can be plated on the surface of the panel to form a thin film by adopting deposition or sputtering. Wherein the deposition comprises methods of Pulsed Laser Deposition (PLD), Chemical Vapor Deposition (CVD), Physical Vapor Deposition (PVD), etc., and the sputtering comprises methods of magnetron sputtering, etc.; different methods are applicable to different substances, and can be selected according to process conditions and product requirements, which are not described herein.

The thermal display layer 2 formed of the thermoluminescent material starts to emit light after being heated to a light emission temperature, where it is at a peak of relative light intensity at a light emission peak temperature. The principle of thermoluminescence: the thermoluminescent material contains a certain concentration of luminescent centers and traps, and free electrons or holes are generated in the crystal under the excitation of light or ray particles, and some of them are trapped by the traps. When the crystal is heated and the temperature is raised, the trapped electrons are thermally excited into free carriers, and when the electrons are combined with the ionized luminescence center, light is emitted. The thermoluminescent material has afterglow after cooling.
The thermoluminescent material adopted by the scheme is in a state of being excited by radiation, namely, thermoluminescent can be generated by heating without being excited again.
As another preferred embodiment, the panel is coated by deposition, sputtering or the like of a pure thermoluminescent substance.

In some embodiments, a thermoluminescent coating contains multiple thermoluminescent material pure substances. Therefore, the luminous colors can be compounded under a certain temperature condition, and the compounding of the colors accords with the principle of three primary colors of colored light: red + green + blue-white; does not conform to the principle of three primary colors (yellow + rose + cyan-black).
The luminous peak temperature of the thermoluminescent material is 50-300 ℃, preferably 80-200 ℃, and the emission spectrum of the thermoluminescent material is within the visible light wavelength range of 380-780 nm; after compounding, coating the mixture on a panel in a spraying, silk-screen printing, pad printing and other modes; or a mixture of thermoluminescent materials is plated on the panel in a deposition, sputtering or other manner; with the rise of the temperature of the panel, a luminous phenomenon appears, such as containing various thermoluminescent materials, and the luminous color can change along with the rise of the temperature of the steps; the light has afterglow lasting for tens of minutes to thousands of minutes. Therefore, not only is display optimization realized, but also the panel temperature is known to be higher than 50 ℃ (if the luminous peak temperature T is known, the temperature higher than T can be further known), even the luminous peak temperature T2 of another thermoluminescent material is known, so that the temperature is additionally indicated, and the user experience comfort is further improved.

When heated and luminous, two circles of luminous rings are generated to indicate the area; of course, it is also possible to cover only one of the outer boundary ring or the inner boundary ring with the thermoluminescent material.
Fig. 6 shows an electric ceramic stove, which is substantially the same as the embodiment of fig. 5, except that the whole stove is circular, the panel 1 is also circular, and the widths of the outer boundary ring and the inner boundary ring are larger than those of the design of fig. 5, so that the thermoluminescence effect is mainly reflected on the inner boundary ring.
In other embodiments, the thermal display layer 2 may intersect the outer boundary of the heating zone 11 or the thermal display layer 2 may be located outside the heating zone 11.
As shown in fig. 7, the outer boundary of the heating region 11 is a closed circular outer boundary ring formed around the periphery of the heating region 11, the heat indicating layer 2 includes a middle pattern layer 22 penetrating the inner and outer sides of the outer boundary of the heating region 11, and the middle pattern layer 22 is an eastern aesthetic style pattern penetrating the inner and outer sides of the outer boundary ring and extending partially along the periphery of the outer boundary ring, which is covered with a thermoluminescent material. When the patterns are heated and emit light, the patterns are solemn without inactivation, and a higher aesthetic experience is brought to users.

The second thermal display layer and the thermal display layer are at least partially overlapped, so that the effect of indicating temperature and the thermoluminescent area are at least partially overlapped, the display optimization of the panel is realized, and the scald-proof warning can be realized.
