Optical system for diopter adjustable head-up display

Abstract

The invention relates to a head-up display optical system for a head-up display. The head-up display is composed of wind window bent glass used for blocking wind from entering a cockpit when transport machines such as an automobile, an aircraft, and a ship move, and optical accessories added to the minimum limit. The optical system does not employ added optical accessories which may have reverse impact on the diopter of the optical system except under the condition that the optical system is formed by less than two curved mirrors, thereby reducing production costs and arrangement difficulty of reflection surfaces; in addition, even curved mirrors are not inclined when moving parallelly, the focus error caused by the production of a head-up display can be effectively compensated and the diopter can be effectively adjusted, thereby minimizing an accessory, and easily and concretely realizing practical and appropriate configurations. Accordingly, the invention provides a head-up display optical system which does not need to perform the complex control used for adding accessories and accurate driving, and can adjust the diopter.

Description

technical field [0001] The present invention relates to a head up display (Head Up Display, HUD), in particular to an optical system for focus adjustable head up display (Optical System for Focus Adjustable Head Up Display) capable of adjusting the diopter. focus error caused by the production of the optical system, and can adjust the diopter of the driver, wherein the head-up display is composed of windshields (windshields) used to block wind from entering the interior of the cockpit when vehicles such as automobiles, airplanes, and ships move. shield) and other curved glass and minimal additional optical components. Background technique [0002] The Head Up Display (HUD), which was introduced for the first time to ensure the front view of the pilot on the plane, is designed to display operating information on the front glass of the plane. In order to reduce accidents, HUD is also being introduced in the automotive field recently. . [0003] The head-up display is the mos...

Problems solved by technology

[0012] For this, the second curved mirror (2 nd Mirror) parallel movement and tilt of another driving source such as a motor, at this time, in order to make the movement amount and the rotation angle correctly linked, the problem that the two driving sources must be controlled by separate electrical signals

In addition, it is difficult to consider the additional components required for this reason and their appropriate arrangement structure, and there is a problem of increasing various costs required for correct programming.
