Abstract

The shading hood comprises a hollow main body having one end corresponding to the shape of the receiver of the optical analyzer and another end inflated outwardly so that the height difference is between the outer and inner surfaces of another end of the main body. It is formed vertically between the gaps, and the gap is formed horizontally between the outer surface and the inner surface of another stage of the main body. When the main body is pushed onto the panel, the panel is pushed by the main body to produce a first color change region outside the receiving area of the receiver facing the panel. In other words, the first color changing area and the receiving area do not overlap, and thus the receiver can receive insomnia light emitted from the panel, allowing the optical analyzer to accurately measure the various physical characteristic parameters of the light.

Shading hood

Description

Shading Hood {SHADING HOOD}

The present invention relates to a shading hood, and more particularly, having one end installed around the receiver of the optical analyzer and another end pushed onto the panel of the color flat panel display to prevent external light from entering the hood. In order to allow the color change zone created on the panel by pressure to be placed outside the receiving zone of the receiver facing the panel, allowing the receiver to accurately measure various physical property parameters of the light emitted from the panel. It is about.

A general way for a color flat panel display to achieve the effect of displaying the expected colors of the display video is to provide known control signal values (R, G, B) of a standard color flat panel display that can exhibit the expected colors. Select and enter each control signal value into the color flat panel display, one by one, corresponding color (e.g., X, Y, and Z three qualifications of the Commission Internationale de I'Eclaiage, abbreviated as CIE) as indicated by the color flat panel display. The signal values are measured and correction is made according to the control signal values R, G, and B so that the color flat display shows the ideal color signal values. It is understood from the above description that it is necessary to first measure the color signal values indicated by the color flat panel display before the color flat panel display shows the ideal color signal values. Currently, two general methods of measuring the color signal values (X, Y, Z) of a panel of a color flat panel display are described below:

1. Non-contact measuring method: In FIG. 1, the optical analyzer 1 is mounted on a fixed stand (such as Tripod) to measure and record various optical characteristic parameters (including color signal values) to measure and record. Obediently placed in position. The measurement conditions of the non-contact panel are very strict; For example, a 90 degree angle is maintained between the optical analyzer 1 and the panel 20, and the measurement must be made in a dark room or the like. This measurement must be carried out in controlled ambient light with many limitations, and therefore its manipulation is inconvenient and unwieldy.

2. Contact Measurement Method: In FIG. 2, the optical analyzer 1 is in contact with a panel 20 which receives light emitted from the panel 2 and measures various optical characteristic parameters (such as color signal values). . In addition, the optical analyzer 1 receives light emitted from a panel in a general environment (instead of only in the dark room) without being affected by other external light in order to accurately measure the various optical characteristic parameters of the panel 20. I can get enough. In Fig. 3, the receiver 10 has a hollow hood 3 made of a silicone gel, and a part of the hood 3 protrudes away from the optical analyzer 1, so that the optical analyzer 1 is paneled. If it is desired to receive the light emitted from 20, the hood 3 is pushed onto the panel 20 so that the hood 3 can be isolated from the external light, so that the optical analyzer 1 requires optical characteristics. In order to measure the parameters, the light emitted from only the panel is received.

In FIG. 4, when the hood 3 is pushed onto the panel 20, the area of the panel 20 facing the periphery of the hood 3 is compressed by the hood 3 and the hood 3. The liquid crystal in the region of the panel 20 facing the perimeter of the liquid is shifted towards the concave objects, so that the color change causes colors output from the region of the panel 20 facing the hood 3, which is referred to as " Color change area ", and the receiving area of the receiver 10 facing the panel 20 includes a color changing area 14, which is emitted from the panel and received by the receiver 10. Will experience a change, so that the various optical characteristic parameters of the light measured by the optical analyzer 1 will not be precise.

In other words, since the color signal values (X, Y, Z) measured by the optical analyzer 1 are not accurate under the above-described conditions, the flat panel display 2 is a color flat display 2. When displaying, it is not possible to obtain accurate correction or ideal color signal values X _T , Y _T , and Z _T.

Summarizing the above description, the non-contact measuring method can measure various physical characteristic parameters without interference by the color change region, but the operation conditions are inconvenient because there are too many restrictions on the measurement conditions. If contact measurement is applied, the optical analyzer 1 may be placed in a desired environment for rapid measurement, but the receiving area 12 is interfered by the color changing area. Therefore, developing an optical analyzer 1 that has the advantages of both measurements and does not have the drawbacks of both methods, the optical analyzer 1 is not disturbed by external lights and the light emitted from the panel 20 is not affected by the panel 20. In order to measure the physical characteristic parameters of the light emitted from the light source, it remains unchanged, requiring emergency care and a usable solution.

In view of the above drawbacks of the prior art, the inventor of the present invention derives the present invention based on many years of experience and research and experiment in the related industry, and devised a shading hood to overcome the drawbacks of the prior art.

The primary object of the present invention is to provide a shading hood having a hollow main body and an end of the main body corresponding to the shape of the receiver of the optical analyzer, wherein the main body can be installed around the receiver, Another end of the main body expands and extends outwardly, with a height difference formed vertically between the outer and inner surfaces of the other end of the main body and horizontally between the inner and outer surfaces of the other end of the main body. It has a gap formed. When the main body is pushed onto the panel, the panel is pushed by the main body to produce a first color change area located outside the receiving area of the receiver facing the panel. In other words, the first color changing region and the receiving region do not overlap, and thus the receiver can receive invariant light emitted from the panel, allowing the optical analyzer to precisely measure the light of various physical characteristic parameters. BRIEF DESCRIPTION OF THE DRAWINGS Preferred embodiments are described in the accompanying drawings in order that the examiner of this article may make it easier to understand the purpose, technical properties and effects of the design.

Referring to FIG. 5 for the shading hood of the present invention, the shading hood has a main body 7, the main body 7 is hollow and the stage of the main body 7 corresponds to the shape of the receiver 50 of the optical analyzer. Thus, the main body 7 can be installed on the receiver 50 and another end of the main body 7 extends outwardly and extends in a direction away from the center of the main body 7. There is a height difference Δh between the outer surface and the inner surface of another stage of) and a gap Δs between the outer surface and the inner surface of another stage of the main body 7. In FIG. 6, when the panel 60 is pushed by the main body 7 and the main body 7 is pushed to the panel 60, the receiving area of the panel 60 facing the receiver 50. (64) The first color change area 62 located outside is calculated. In other words, the first color changing area 62 and the receiving area do not overlap so that the receiver 50 can receive the invariant light emitted from the panel 60 so that the optical analyzer can adjust various physical characteristic parameters of the light. It can be measured.

In FIG. 7, at least one central hood 70 is arranged between the outer surface and the inner surface of another end of the main body 7, and one end of the central hood 70 is the main body 7. Another end of the center hood 70 extends outwardly such that an extended length of the center hood 70 is formed vertically between the outer surface and the inner surface of another end of the main body 7. The second color change area 66, classified by the height difference Δh and calculated by pushing the central hood 70 onto the panel, is also outside the receiving area 64 (as shown in FIG. 8). .

Summarizing the above description, the shading hood will be pushed to the panel 60 so that the outside light of the shading hood will not fall within the area confined by the per shading hood, and the shading hood will be pushed to the panel 60 to shading hood. Because of the compressive force of the color change areas 62, 66 calculated by the panel 60 will not be included in the receiving area 64, the central hood 70 is shading attached to the panel 60. Since the safety of the hood can be improved, the receiver 50 and the panel 60 can be kept at right angles to each other to measure various physical property parameters, which is a problem of conventional shading hoods that cannot accurately measure physical property parameters. Will improve.
