Abstract

The embodiment of the invention discloses an infrared touch screen and encapsulation method of filter strip; the infrared touch screen comprises a side frame, a touch detection area, an infrared transmission tube, an infrared receiving tube and a filter strip; the side frame consists of an upper cover, a lower cover and an external side cover. A slot is arranged on at least one surface of the lower surface of the upper cover of the side frame and the upper surface of the filter strip, and / or a slot is arranged on at least one surface of the upper surface of the lower cover of the side frame and the lower surface of the filter strip; the sealing materials are filled in the slot. The sealing materials are filled in the whole slot via the irrigation manner and are permeated to the gap on two sides of the slot between the upper and lower covers of the side frame and the upper and lower surfaces of the filter strip; and a dish-shaped or approximately dish-shaped sealing structure is formed in the slot and the gap by the sealing materials. The infrared touch screen and encapsulation method of filter strip has good sealing performance; the filter strip is not easy to be dropped, so that it is applicable to the batch production.

Description

technical field [0001] The invention relates to the field of touch screens, in particular to the field of a packaging method for a filter strip used in an infrared touch screen. Background technique [0002] Infrared touch screen technology is already a well-known technology, which has the advantages of large size, multi-touch, high light transmittance, etc., and is widely used. An important feature of the infrared touch screen is that it must have an infrared light-transmitting frame to ensure that the light received by the infrared receiving unit is infrared light, thereby reducing the interference of ambient light. In the infrared touch screen technology, two methods are often used to set the light-transmitting frame: 1. The frame of the infrared touch screen is made of optical materials that can transmit infrared light and block visible light; 2. The frame is made of opaque material, which is packaged on the frame of the infrared touch screen Infrared filter strips. In...
