Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Example one
Detailed descriptionan embodiment of the present invention provides a carbon monoxide sensor integrated on a tv panel.
Referring to fig. 1a, the carbon monoxide sensor 103 is located in the non-display area 102 of the front surface of the tv panel 10.
In this embodiment, the tv panel 10 is divided into two regions: a display region 101 and a non-display region 102, and a thin film transistor is formed in the display region 101. The carbon monoxide sensor 103 is integrated in the non-display area 102 of the television panel 10, so that the non-display area is fully utilized, and the use area of the television panel is increased. A bonding region 104 is also disposed in the non-display region 102.
Referring to fig. 2a and 2b, the carbon monoxide sensor 103 comprises an electrode layer 1031, an insulating layer 1032, a heating electrode layer 1033, and a sensing layer 1034, wherein the electrode layer 1031 comprises two independent regions;
the insulating layer 1032 is located between two independent regions of the electrode layer 1031;
the heating electrode layer 1033 is located on the upper surface of the insulating layer 1032;
the sensitive layer 1034 is located on the upper surface of the heating electrode layer 1033.
In this embodiment, the carbon monoxide sensor works on the principle that the resistivity of the carbon monoxide gas adsorbed by the sensitive material changes, and the change of the resistivity is monitored to judge the carbon monoxide gas concentration in the environment. The sensitive layer 1034 forms a resistor for adsorbing carbon monoxide gas. Two ends of the sensitive layer 1034 are respectively connected to two independent regions of the electrode layer 1031, and the left and right portions of the electrode layer in the cross-sectional view of the carbon monoxide sensor shown in fig. 2b are two independent regions of the electrode layer 1031. An insulating layer 1032 is located between two separate regions of the electrode layer 1031 for isolating the two electrodes. Heating electrode layer 1033, when heated, increases the sensitivity of sensing layer 1034 to changes in resistance.
Preferably, the carbon monoxide sensor 103 further comprises a heat sink 1035, the material of the heat sink is coated with a graphite sheet or carbon nanotubes;
the heat sink 1035 is attached to the back of the tv panel 10 in an area corresponding to the carbon monoxide sensor 103.
In this embodiment, since the local temperature of the tv panel 10 will increase after the heating electrode layer 1033 is heated by the carbon monoxide sensor 103, the heat sink 1035 is adhered to the back surface of the tv panel 10 in the area corresponding to the carbon monoxide sensor 103, so as to avoid damage caused by the local temperature of the tv panel being too high. The material of the heat sink 1035 may be a graphite sheet, a carbon nanotube coating, or other materials, which is not limited in detail in this embodiment of the present invention and can be selected according to actual situations.
In fig. 2a and 2b, the heating electrode layer 1033 of the carbon monoxide sensor 103 is in a complete rectangular pattern, and preferably, the heating electrode layer 1033 can also be in a grid pattern as in fig. 3a and 3b, and the grid pattern is used to facilitate heat dissipation of the heating electrode layer. The heating electrode layer may also adopt other patterns, which is not limited in detail in the embodiment of the present invention and may be selected according to actual situations.
The sensitive layer 1034 may be made of tin dioxide, a composite material of tin dioxide and platinum, or other sensitive materials, which is not limited in this embodiment of the present invention in detail, and may be set according to actual situations.
In this embodiment, one or more carbon monoxide sensors may be integrated in the non-display area on the front surface of the upper panel of the television, and preferably, at least two carbon monoxide sensors are integrated in the non-display area on the front surface of the upper panel of the television. If only one carbon monoxide sensor is integrated, when the carbon monoxide sensor cannot work normally, the intelligent television loses the function of detecting the carbon monoxide gas concentration in the environment. And at least two carbon monoxide sensors are integrated, if one of the carbon monoxide sensors cannot work normally, the other carbon monoxide sensor can also detect the carbon monoxide gas concentration in the environment. For example, four carbon monoxide sensors are integrated in the non-display area on the front surface of the television panel, and referring to fig. 1b, if the carbon monoxide sensor No. 1 cannot work normally, the carbon monoxide sensor No. 2, 3 or 4 can also be started to detect the carbon monoxide gas concentration in the environment. The number of the integrated carbon monoxide sensors is not limited in detail in the embodiment of the invention, and the number can be set according to actual conditions.
In summary, in the embodiment of the present invention, the carbon monoxide sensor is located in the non-display area on the front surface of the television panel, which does not affect the display of the television panel, and makes full use of the non-display area, thereby increasing the usable area of the television panel. The carbon monoxide sensor comprises an electrode layer, an insulating layer, a heating electrode layer and a sensitive layer, wherein the electrode layer comprises two independent areas; the insulating layer is positioned between two independent areas of the electrode layer; the heating electrode layer is positioned on the upper surface of the insulating layer; the sensitive layer is positioned on the upper surface of the heating electrode layer. According to the embodiment of the invention, the carbon monoxide sensor is designed to be in a semiconductor type and can be integrated on the television panel, so that the cost is saved compared with the cost of independently manufacturing the packaged carbon monoxide sensor.

In this embodiment, after the heating electrode layer of the carbon monoxide sensor is fabricated, the sensitive layer of the carbon monoxide sensor is fabricated on the heating electrode layer. Specifically, photoresist is used for covering the regions of the front surface of the television panel except the carbon monoxide sensor sensitive layer, in particular covering the display region of the front surface of the television panel; after the photoresist is covered, the sensitive material is sputtered, the sputtering process and the thickness of the sensitive material are not limited in detail in the embodiment of the invention, and the arrangement can be carried out according to the actual situation. After the sensitive material is sputtered, the photoresist is removed, and the process for removing the photoresist is not limited in detail in the embodiment of the invention and can be selected according to actual conditions.
After the manufacturing process of the carbon monoxide sensor on the front side of the television panel is finished, the radiating fins are adhered to the area, corresponding to the carbon monoxide sensor, of the back side of the television panel, wherein the radiating fins are made of graphite sheets or carbon nano tube coatings.
