Description

1274523 IX. Description of the Invention: [Technical Field] The present invention relates to a heating device for an electrothermal touch input device, and a low temperature range of the touch input device. [Prior Art] As shown in the figure IX, the general touch panel (50) is mainly formed on the front and rear transparent substrates (5 2 ) ( 5 1 ) (sputtered/coated) with a transparent electrode layer (5). 2 0 ) ( 5 1 0 ) (indium tin oxide layer; ITO) and silver Γ R Ρ Ί \ / J— 丄) (5 1 1 ), and then two transparent substrates (5) 2) ( 5 1 ) separated, in which the silver wires (5 2 1 ) ( 5 1 1 ) of the two transparent substrates (5 2 ) (5 1 ) are connected with the external wires (6, so that when the transparent substrate is When pressed, the transparent electrode layers of the two transparent substrates (5 2 2 i 5 1 ) are contacted and short-circuited corresponding to the pressing position, and the external circuit can obtain the voltage value through the wiring, and then determine the position of the dust by the voltage value. 〇Because the touch panel can replace some of the independent input devices (such as buttons, ., force plus this - the technical field of materials and process technology 亦 = also a variety of electronic products man-machine interface needs 35, making touch The control surface consists of:::...and 1' part of the electronic products are used according to outdoor use, :::: Relatively the requirements of the electronic components or circuits for the working environment, say, the general touch panel heart; Large pair of touch surfaces (four) Negative temperature range of ten degrees to sixty degrees, the temperature range is about the name), the world's low operating temperature (Celsius negative clothes i brother / dish is lower than Celsius g when touch If the panel is outside, w, or ten degrees, it will be less than its minimum operating temperature, but it will be 3 8 1274523. It may not be used. This is why it is due to the touch panel. Due to the material properties of the transparent electrode layer, since the thickness of the transparent electrode layer formed on each transparent substrate is relatively thin (about 1 〇 1 〇〇 μ), the transparent electrode layer may be oxidized and crystallized as the temperature changes. And change its resistance value, so 'when the cable input - fixed battery detection according to the resistance value of the repeated position, will = transparent: the resistance value of the moon electrode layer is changed by the temperature change, and there is positioning: t ^ door In addition, the problem is that in the low temperature environment, there will be fog condensation on the second:: the problem, causing the surface of the surface to be blurred and unclear, the effect is obvious because the touch panel itself is not _ 艿 + eight 旦 顦 顦 顦The function needs to be combined with a display at the rear substrate. With a + private strike and then into the touch input I set, and the common display is not a flat LCD, but because of the normal minimum recording in the flat LCD display / night, w _ red The k-degree can not be lower than zero degrees Celsius, and the liquid crystal display will also work abnormally in a low-temperature environment. At present, there are many problems caused by the change of the electrode compensation by changing the electrode. #仁部 Relatively Change the side of the original touch panel, the design of the controller, ^ ^ ^ ^ ^ is not a good solution, and the manufacturer is trying to change the coating technology; ^ Μ ':... and the target' so that the transparent electrode layer has The stability at lower temperatures is not as effective as the current one. In view of the current touch; ^ age λ workers input clothes have low temperature operation is not easy to fog and other issues, so the % and easy to produce ^ propose a solution to expand the scope of 1. L is inferior [invention] For this reason, the main i of the present invention

The purpose is to provide an electric heating type _ @ ^ # setting heating device, that is, add an additional 8 1274523 at the appropriate position of the control input I 蜀 control wheel intrusion position: when the ambient temperature is close to the minimum operating temperature, Start control 2:; Two hot devices increase the temperature of the touch input device, making it touch. The temperature of staying is not lower than the minimum operating temperature, and the normal touch input device is mainly composed of a touch device.
