Touch all-in-one computer water and fog resistance detection device and method

Abstract

The invention relates to a touch all-in-one computer water and fog resistance detection device and method. The device comprises a reflectivity detector for detecting glass screen surface reflectivity of a touch all-in-on computer, a data processor electrically connected with the reflectivity detector, a detection box provided with a containing cavity, a temperature controller for controlling the temperature of the containing cavity, and a humidifier for controlling the relative humidity of the containing cavity; the detection box is further provided with a detection window communicated with the containing cavity; the reflectivity detector is arranged on the detection window. When the device is used for detecting, the touch all-in-one computer is placed in the containing cavity of the detection box, the temperature change and humidity change in the detection box are controlled through the temperature controller and the humidifier, and the reflectivity detector and the data processor acquire whether the touch all-in-one computer has water fog under different temperatures and humidifies, thereby detecting the water fog resistance of the touch all-in-one computer, the current water fog resistance scheme is modified or improved according to the water fog appearance condition; the device can prevent the glass screen of the touch all-in-one machine from the water fog, and the user experience is improved.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a device and method for detecting the waterproof and fog performance of a touch all-in-one machine. Background technique [0002] With the development of technology, touch technology is widely used in various electronic devices, such as smart phones, tablet computers and various touch all-in-one machines with larger sizes. Such as figure 1 As shown, the existing touch all-in-one machine 100 is generally formed by sequentially assembling a touch frame 10, a frame 20, a glass screen 30, a display screen 40, a connector 50 and a rear cover 60, wherein the glass screen 30 covers the display screen 40, To play the role of protecting the display screen 30 . After the actual assembly, there will be a certain gap between the glass screen 30 and the display screen 40. When the external temperature changes greatly, such as when the temperature suddenly rises or drops suddenly, the water v...

Problems solved by technology

After the actual assembly, there will be a certain gap between the glass screen 30 and the display screen 40. When the external temperature changes greatly, such as when the temperature suddenly rises or drops suddenly, the water vapor between the display screen 40 and the glass screen 30 may Condensation forms water mist on the glass screen 30, causing local refractive index of the glass screen 30 to occur, and then the display position of the display screen 40 is displayed abnormally, and the user experience is not good

In response to this problem, various manufacturers will provide corresponding anti-fog solutions, but how effective the specific anti-fog solutions can bring, and whether they can really meet the needs of various use environments, there is no verification method and standard yet. , which makes it impossible to determine the reliability of many touch all-in-one machines even after rectification, resulting in frequent occurrence of water mist during use, affecting user experience
