Nixie tube with infrared touch function

Abstract

The invention discloses a nixie tube with an infrared touch function. The nixie tube comprises a PCB, a plastic shell and a light emitting lamp wick, wherein the light emitting lamp wick is located onthe PCB; an infrared transmission tube and an infrared reception tube are arranged on the PCB; an infrared ray transmitted by the infrared transmission tube obliquely penetrates through the plastic shell; a window for being touch by a finger and shielding the infrared ray by utilizing the finger is arranged at a place, where the infrared ray penetrates, on the surface of the plastic shell; the infrared reception tube is used for receiving the infrared ray which is reflected through the shielding of the finger; and the infrared reception tube is connected with a driving chip which is used forcontrolling the light emitting lamp wick. The action of finger touch and an infrared ray reflection principle are applied into the nixie tube, so that the touch display function of the nixie tube is realized, the touch function can be stable and effective in a long time, and the realization of the touch function is not limited by the space and structure of the nixie tube; and the nixie tube is suitable for any nixie tube structures and has extremely high application universality.

Description

technical field [0001] The invention belongs to the technical field of digital tubes, in particular to a digital tube with an infrared touch function. Background technique [0002] Many existing nixie tubes have touch control functions, which are mainly realized by installing springs or capacitive films. Because the cost of capacitive films is very high, most manufacturers still choose to install springs, but this method has the following disadvantages : [0003] 1. After the spring is used for a period of time, it is very easy to twist and deform, causing the structure and position of the spring to deviate, resulting in poor contact of the touch function, and even failure of the touch function; [0004] 2. The installation of the spring has certain requirements for the size of the space, so that some digital tubes with small internal space cannot meet the installation requirements of the spring. Contents of the invention [0005] Purpose of the invention: In order to ov...
