Touch all-in-one machine anti-fog performance testing device and method

Abstract

Provided are a device and method for measuring the fog-prevention performance of a touch-control all-in-one machine (100), comprising a reflection meter (230) used for measuring the surface reflection of a glass screen (30) of the touch-control all-in-one machine (100), a data processor electrically connected to the reflection meter, a measurement bin provided with an accommodating cavity, a temperature controller used for controlling the temperature of the accommodating cavity, and humidifier used for controlling the relative humidity of the accommodating cavity; the measurement bin (210) is also provided with a measurement window (211) in communication with the accommodating cavity; the reflection meter (230) is disposed on the measurement window (211). During measurement, the touch-control all-in-one machine (100) is placed inside the accommodating cavity of the measurement bin (210); changes of the temperature and humidity inside the measurement bin (210) are controlled by means of the temperature controller and the humidifier, and whether water / fog is present on the touch-control all-in-one machine (100) at different temperatures and humidities is obtained by means of the reflection meter (230) and the data processor; thus the water- and fog-prevention performance of the touch-control all-in-one machine (100) is measured; according to the situation of water and fog appearing, the current fog-prevention scheme is corrected or modified, thereby preventing the appearance of fog on the glass screen of the touch-control all-in-one machine (100) and improving user experience.

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
