Connector for optical sensor and substrate, method for manufacturing optical sensor

Abstract

The present invention discloses a connector of connecting a light sensor and a substrate utilized for rotating the light sensor so that the light-receiving direction of the light sensor is parallel with the substrate. When the connector is utilized in an optical touch system, the light sensor can be disposed on the substrate of the optical touch system by means of general manufacturing facilities of flat display panels. Meanwhile, the light-receiving direction of the light sensor is parallel with the substrate of the optical touch system.

Description

technical field [0001] The present invention relates to a connector, more specifically, to a connector for connecting an optical sensor and a substrate and a manufacturing method of the optical sensor. Background technique [0002] The optical touch system includes a display screen, a transparent substrate, a light sensor, and a position calculation circuit. Generally speaking, the transparent substrate is a glass substrate, more specifically, the transparent substrate is a Tin-doped Indium Oxide (ITO) glass. The display screen displays images through a transparent substrate. The light sensor is a chip module, the light sensor needs to be arranged on the transparent substrate, and the light receiving direction of the light sensor must be parallel to the transparent substrate. In this way, the light sensor can detect whether there is an indicator (such as a finger, a stylus) on the transparent substrate, and generate a light sensing signal accordingly. For example, the lig...

Problems solved by technology

In other words, in the optical touch system, if the user intends to use the existing packaging method (such as TCP or COF) to place the light sensor on the glass substrate, the light receiving direction of the light sensor is perpendicular to the glass substrate, resulting in The light sensor cannot detect that a pointer (such as a finger, stylus) is in contact with the display

Although in the known technology, the user can bend the soft board at an angle and then fix the soft board to transpose the light receiving direction of the light sensor, but this process can only be handled manually, and this process is time-consuming and expensive. The yield rate is not easy to control, so it will increase the cost of the optical touch system and bring great inconvenience to users
