Image guidance assembly for optical mouse

Abstract

Disclosed herein is an image navigation module for an optical mouse. The image navigation module includes a module unit and a lid type prism-integrated lens. The module unit is constructed in such a way that a light emitting element and a sensor die are constructed on a board in a chip-on board manner. The lid type prism-integrated lens is put on the board to cover regions where the light emitting element and the sensor die are constructed. The sensor die is a single chip sensor into which an image sensor for detecting light converged by the lid type prism-integrated lens and a Main Control Unit (MCU) for processing detected signals are integrated.

Description

Technical field [0001] The present invention generally relates to an image navigation module for an optical mouse, and more specifically, to an image navigation module for an optical mouse, in which a sensor chip (sensor chip) integrating an image sensor and a main control unit is constructed. die), and a chip-on-board light-emitting diode on a printed circuit board, and the combination of a small lens with a printed circuit board, a sensor chip and a light-emitting diode constructed on it, to modularize the image navigation mechanism, thereby increasing The sensing efficiency of the image navigation mechanism and the reduction of the manufacturing cost of the optical mouse can improve the performance of the optical mouse. Background technique [0002] A mouse, which is a type of input device used in a computer, is a device used to directly or indirectly point the coordinates of a cursor or pointer in a computer. This type of mouse is divided into two types: ball mice that use th...

Problems solved by technology

[0025] Assembling discrete parts into an optical system such that the performance of the optical mouse is degraded due to assembly deviations of the discrete parts, therefore, readout errors occur, resulting in increased performance deviations of the optical mouse

[0026] In addition, the discrete parts can be manually assembled into the optical mouse, resulting in inefficient assembly work, low assembly efficiency for workers and increased assembly time

[0027] The number of parts is so high that it increases the manufacturing cost of the optical mouse, which requires an improvement in the number of parts
