Embodiment Construction

[0012] The thermal printing head and the thermal printing system provided by the embodiment of the technical solution will be further described in detail below with reference to the drawings and multiple embodiments.

[0013] see figure 1 , the thermal print head 10 provided by the first embodiment of the technical solution includes a print head 11 and a heating device 12 .

[0014] The heating device 12 includes an insulating substrate 121 and a heating component 122 disposed on the insulating substrate 121 . The insulating substrate 121 may be a dielectric material substrate. The heating element 122 includes a pair of electrodes 122a and a resistance heating film 122b disposed between the pair of electrodes 122a. The resistive heating film 122b has a resistance greater than 100Ω / □, such as indium tin oxide film, aluminum-doped zinc oxide film, etc., and is electrically connected to the electrode pair 122a for converting electrical energy into thermal energy. Among them, "...

Description

technical field [0001] The invention relates to the technical field of thermal printing, in particular to a thermal printing head and a thermal printing system. Background technique [0002] Thermal printing technology is a printing technology that completes text and image output by controlling the heating and cooling of the heating element of the thermal printing head to change the color of the printing medium by heating, or to melt / sublimate the dye to color the medium. Please refer to the literature on thermal print heads published at the 36th International Electronic Circuits Conference (36th ISSCC.) in 1988: Hayashi Y., Hayashi H., Neyishi M., Matsushita T., Yagino M., Endo T., A Thermal Printer Head With Cmos Thin-film Transistors And Heating Elements Integrated On a Chip, Digest of Technical Papers., 1988 IEEE International. [0003] A thermal printhead generally includes a heat generating body that supplies heat. However, the heating element currently used is tanta...
