Embodiment Construction

[0030] Refer to the following Figure 2 to Figure 5 , to describe the typical embodiments of the present invention in more detail.

[0031] figure 2 It is a schematic diagram of the partial configuration of the optical engine 200 of the projection type image display device according to the exemplary embodiment of the present invention. and figure 1 Devices with the same constituent elements are denoted by the same reference numerals, and repeated description thereof will be omitted.

[0032] refer to figure 2 Visible, with figure 1 Unlike the conventional optical engine 100 shown, the optical engine of the present invention consists of two light sources ( 10 , 20 ) and a cut-off screen 30 . The first light source 10 includes, for example, a high-intensity emission (HID) light source; the second light source 20 includes, for example, a halogen light source. The function of the cut-off screen 30 is to cut off the light emitted by the light sources (10, 20). If the power...

Abstract

The invention comprises: an optical engine comprising a firs light source, a second light source with halogen lamp source and a cutting-off screen for cutting off the reflecting light from the first light and second light sources; a controller, for controlling the first light source, the second light source and the cutting-off screen, which is composed of a light source detector used to detect the stability of light source, a cutting-off screen adjuster used to cut off the reflecting light from the first light source before getting a stability of the first light source and to cut off the reflecting light from the second light source after getting the stability of the first light source, a power controller used to cut off the second light source after getting the stability of the first light source.

Description

technical field [0001] The present invention relates to a projection-type image display device, in particular to a projection-type image display device which can display images on a screen quickly by using a second light source and its working method. Background technique [0002] In recent years, with the development of the information industry, the demand for image display devices capable of displaying large screen images is increasing. Among them, the image display device equipped with an optical engine together with a liquid crystal display (LCD) rear projection and a liquid crystal display (LCD) projector is smaller in size and weight than the existing cathode ray tube (CRT) products, and compared with Liquid crystal display (LCD) and plasma display products are competitive in price, so this product is valued by consumers who like large screen images. [0003] figure 1 It is a schematic diagram of the structure of the optical engine 100 in a conventional liquid crysta...
