Embodiment Construction

[0011] Since the size, color and brightness of the digital tubes used in various instruments are different, the light transmittance of the protective screen glass and the distance between the protective screen and the digital tube are also quite different. The glass film is also different. How much light transmittance to use for automotive glass film must be determined through experiments.

[0012] The experimental method is: under strong outdoor light, cover the car glass film on the protective screen glass of the digital tube of the instrument, and observe the digital tube numbers through the glass film when the digital tube is powered off, so as to vaguely see the digital tube numbers.

[0013] In the power-off state, if the digital tube numbers are still bright through the car glass film, it means that the light transmittance of the selected car glass film is high, and the car glass film with lower light transmittance should be replaced.

[0014] In order to make the ligh...

Abstract

The invention relates to an LED digital tube display method under strong light through a screen pad pasting method. In order to make a digital tube to display under strong light, the method of pasting an automotive glass film on a protective screen of the digital tube is used. After the automotive glass film with suitable light transmittance is pasted on the protective screen of the digital tube, incident intensity is reduced, and reflected light intensity of the digital tube is smaller than the own illumination intensity of the digital tube. In this way, people can directly see numbers displayed on the digital tube under strong light without shading.

Description

[0001] Technical field [0002] The invention relates to a method for displaying LED digital tubes under strong light. Background technique [0003] LED digital tubes have the advantages of accurate display, convenient reading, and low price, and have been widely used in various fields. However, LED digital tubes have a significant defect, that is, people cannot distinguish the numbers displayed by the digital tubes under strong outdoor light. Even turning up the brightness of the nixie tube doesn't help. In order to read the numbers displayed by the nixie tube of the meter, the user has to block the light with hands or other objects, and sometimes even covers the head and the meter with clothes. This causes great inconvenience to the meter user. Contents of the invention [0004] When the light is irradiated on the LED digital tube, the segments that make up the digital will reflect the light. When the ambient light is strong, the reflected light intensity of the digita...
