본 고안은 프러젝션(Projection)TV의 스크린(Screen)에서 렌티큘러렌즈의 입사측과 출사측의 렌즈 엘리먼트를 비구면, 비대칭으로 구성하여 사용자가 원하는 시청각도에서 최대의 게인(Gain)을 얻을 수 있도록 한 프러젝션 TV의 스크린용 높은 게인을 갖는 렌티큘러렌즈에 관한 것이다.The present invention is designed to obtain the maximum gain at the desired viewing angle by assembling the aspherical and asymmetrical lens elements on the entrance and exit sides of the lenticular lens on the screen of the projection TV. A high gain lenticular lens for a screen of a projection TV.

최근 정보사회의 발전에 따라 정보발달수단으로서 디스플레이(Display)에도 고기능화, 대형화의 요구가 증대하고 있다. 그일예로서 현재 현저한 발전이 이루어지고 있는 분야가 프러젝션 TV이다. 이는 TV의 대형화 기술로서 반사형과 투과형으로 크게나뉘지만 명실공히 사용이 가능한 것과 콘소울(Console)형으로서 보통 TV의 연장선상에서 생각되어 지기 때문에 투과형이 주류로 되어 있다.Recently, with the development of the information society, the demand for high-functionality and large-sized display is increasing as a means of information development. For example, projection TV is one of the areas where significant progress is being made. This is a large-sized technology of TV, which is largely divided into reflection type and transmission type, but transparent type can be used clearly, and as a sole type, it is considered to be an extension of TV.

이 투과형의 스크린은 CRT에서의 확산광을 평행광으로 변환하기 위한 서큐럴 프레스넬 렌즈(Circular fresnel lens)와 일정광량의 빛을 유효하게 이용하기 위하여 관시범위만으로 빛을 분배하는 작용을 갖는 렌티큘러렌즈(Lenticular Lens)와의 조합으로 되어 있다.This transmissive screen has a circular fresnel lens for converting diffused light from a CRT into parallel light and a lenticular lens having a function of distributing light only through a viewing range in order to effectively use a certain amount of light. It is in combination with (Lenticular Lens).

여기에서 본 고안은 렌티큘러렌즈에 관한 고안인 것으로 종래에는 렌티큘러렌즈에 게인을 높여주기위한 구성이 미비하여 사용자가 원하는 시청각도에서의 시청이 곤란하였다.Herein, the present invention relates to a lenticular lens. In the related art, a configuration for increasing the gain of the lenticular lens is insufficient, so that viewing at a viewing angle desired by a user is difficult.

따라서, 본 고안의 목적은 상기와 같은 종래의 문제점을 해결하기 위하여 안출된 것으로 프러젝션 TV의 스크린에서 렌티큘러렌즈에 수평 또는 수직으로 렌즈엘리먼트를 비구면, 비대칭으로 함으로써 필요한 방향에서의 최대 게인(Gain)을 갖도록 함에 그 목적이 있는 것이다.Accordingly, an object of the present invention is to solve the above-mentioned problems. As a result of aspheric and asymmetrical lens elements on the projection TV screen, the maximum gain in the required direction is made aspheric or asymmetrical to the lenticular lens. The purpose is to have a.

이하, 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings as follows.

먼저, 도시된 제 1도에 의하여 설명한다.First, a description will be given with reference to FIG. 1.

프로젝션 TV의 스크린으로서 구성되는 프레스넬 렌즈(1)와 렌티큘러 렌즈(2)는 도시된 제 2도에서와 같이 수평방향으로 입사측과 출사측에 비구면, 비대칭의 렌지 엘리먼트(3)(4)를 형성하고 또한 도시된 제 3도 에서와 같이 수직방향으로 비구면, 비대칭의 렌즈엘리먼트(3)(4)를 형성하여서 된 것이다.The Fresnel lens 1 and the lenticular lens 2, which are configured as the screen of the projection TV, have an aspherical, asymmetrical range of lens elements 3, 4 on the incidence and exit sides in the horizontal direction as shown in FIG. And aspherical, asymmetric lens elements 3 and 4 in the vertical direction as shown in FIG.

이상과 같이된 본 고안의 프레스넬렌즈(1)는 CRT(5)에서의 확산광을 평행광으로 변환하기 위한 기능을 가지고 있고, 렌티큘러렌즈(2)는 일정광량의 빛을 유효하게 이용하기 위하여 관시범위만으로 빛을 분배하는 작용을 하는 것인데, 이들이 결합되어 도시된 제 4도에서와 같이 프러젝션 TV(6)의 전방에 설치되어 스크린(7)의 기능을 갖는다.The Fresnel lens 1 of the present invention as described above has a function for converting the diffused light in the CRT (5) into parallel light, the lenticular lens (2) in order to effectively use a certain amount of light It serves to distribute the light only in the viewing range, which is installed in front of the projection TV 6 as shown in FIG. 4 in combination to have the function of the screen 7.

그런데, 상기의 렌티큘러렌즈(2)에서 입사측과 출사측에 수평, 수직방향으로 비구면, 비대칭의 렌즈엘리먼트(3)(4)를 구성함에 따라 도시된 제 5도의 (a)(b)에서와 같이 수평, 수직의 어느시청방향에서도 최대의 계인을 얻을 수 있게되는 것이다.However, in the lenticular lens 2, as shown in (a) and (b) of FIG. 5, as shown in FIG. 5, as shown in FIG. Likewise, the maximum factor in both horizontal and vertical viewing directions can be obtained.

Claims (1)

프로젝션 TV의 스크린으로서 구성되는 렌티큘러렌즈에 있어서, 상기의 렌티큘러렌즈는 입사측과 출사측에 수평, 수직방향으로 비구면, 비대칭의 렌즈 엘리먼트를 형성하여서 된것에 있어서, 블랙 스트라이프의 사이사이에 수직방향으로 비구면, 비대칭의 렌즈 엘리먼트를 형성하여 필요한 각도에서의 최대 게인을 얻을 수 있도록 구성하여서 된것을 특징으로 하는 프러젝션 TV의 스크린용 높은 게인을 갖는 렌티큘러렌즈.In a lenticular lens configured as a screen of a projection TV, the lenticular lens is formed by forming an aspherical, asymmetric lens element in the horizontal and vertical directions on the incidence side and the outgoing side in the vertical direction between the black stripes. A lenticular lens having a high gain for a screen of a projection TV, characterized by forming an aspherical, asymmetric lens element so as to obtain a maximum gain at a required angle.
