Problems solved by technology

In the existing technology, the sensor can only achieve a thickness of millimeters, generally more than a few millimeters thick, and cannot be embedded in flat film components
At the same time, the diameter of the traditional signal transmission line is relatively thick, and the general circular wire cannot bear the huge pressure between the two flat surfaces. Under this pressure, the wire is easily damaged, and the signal cannot be transmitted in the film and the slit.
Therefore, sensors and transmission lines in the traditional sense cannot solve the problem of collecting and transmitting signals in the slit

Embodiment 1

[0041] This embodiment provides a thin-film acquisition and transmission device for temperature signals, that is, a temperature detector, whose structure is as follows figure 2 with image 3 shown ( figure 2 The middle dotted line indicates that the length of the temperature detector can be determined according to the actual situation), including the thinned temperature sensor 6 and the planar transmission line, the thickness of the thinned temperature sensor 6 is less than 0.3mm, the thickness of the planar transmission line is less than 0.2mm, and the planar transmission line includes two The basic insulating layer 4 and the metal lead 3, the input electrode 1 and the output electrode 2 arranged between the two basic insulating layers 4, the metal lead 3 is a copper wire, one end of the metal lead 3 is connected to the input electrode 1, and the other end is connected to the output electrode 2. The output electrode 2 is connected to the processor, and the input electrode ...

Embodiment 2

[0052] The difference between this embodiment and embodiment 1 is: as Figure 4 As shown, the transmission line of the temperature detector includes an input electrode 1 and an output electrode 2. Both the input electrode 1 and the output electrode 2 are tinned pads of an 8-pin package, and the input pin of the input electrode 1 is connected to the The corresponding output pin of the output electrode 2 is connected.

[0053] In addition, in practical applications, the temperature detection sensor can use a negative temperature coefficient thermistor or a temperature acquisition chip, such as DS18B20, AD590, TMP35, TMP36 and other chips. If the temperature acquisition chip chooses SO surface mount package, it can also be used Grinding and thinning treatment, and then design the input and output electrodes that meet the package according to the specifications of the selected chip.

Embodiment 3

[0055] The difference between this embodiment and Embodiment 1 is that: taking a 15-inch LCD screen as an example, at least 4 sensors are required to accurately collect the temperature in the screen if the temperature in the screen is to be collected, and the 4 sensors are placed on the screen. The four corners are the most stable way to collect temperature. Such as Figure 5 As shown, a temperature detector using a thermistor as a sensor includes four input electrodes and four output electrodes, and the four input electrodes are input electrode one 1-1, input electrode two 1-2, input electrode two The third electrode 1-3, the fourth input electrode 1-4, and the four output electrodes are respectively the first output electrode 2-1, the second output electrode 2-2, the third output electrode 2-3, and the fourth output electrode 2-4. Each input electrode is welded with a temperature sensor, and the four temperature sensors are respectively arranged at the four corners of the l...

Description

technical field [0001] The invention relates to a data acquisition and transmission device and method, more specifically to a thin-film acquisition and transmission device and method for liquid crystal temperature signals, belonging to the technical field of electronic equipment temperature monitoring. Background technique [0002] At present, liquid crystal screens have been widely used, but limited by the performance of liquid crystal materials, liquid crystal screens can only work normally within a narrow temperature range, so the use effect of liquid crystal screens is closely related to the temperature environment. As we all know, if you want to control the temperature of the LCD screen of a tablet computer, you must install a temperature sensor component inside the LCD glass screen. However, due to the multi-layer compact flat structure of the LCD screen, if you want to insert sensors and Transmission lines are a very difficult thing. After searching, it is found that...
