Abstract

PURPOSE:To make the screen of a high-accuracy color display tube more easily seen by making the curves of the upper and the lower long sides of the effective area of the high-accuracy color display tube, which is used for a display apparatus installed at the terminal of a computer, different from one another. CONSTITUTION:The shape of the effective area 3 of a high-accuracy color display tube which is used for an display apparatus for a personal computer, is set so that the curve radius (R2) of the upper long side is smaller than the curve radius (R1) of the lower long side. As a result, when a computer operator observes at close range by taking a sight distance of 30-50cm from the display tube, the effective area 3 can be seen as a symmetrical shape relative to the horizontal center line. Consequently, the screen of the display tube is made much more easily seen, and any wrong graphic information which might be caused dependently on the shape of the effective area 3 can be prevented.

ζこ関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improving the visibility of the effective surface shape of a high-definition color display tube of a computer terminal display device, particularly a personal computer display device.

When viewing from a viewing distance of 3 to 5 meters, it can be said that the effective surface is vertically and horizontally symmetrical, which is optimal in terms of ease of viewing the screen.

の色純度、白色ムラ特性上都合良くない。However, in the case of display tubes used in display devices for computer terminals, the viewing distance is 30 to 50 meters, making viewing the display tube extremely close.
The shape of the effective surface (this raises the issue of how easy or difficult it is to see the screen).In particular, in order to improve the work efficiency of computer operators and reduce eye fatigue, a structure in which the display tube surface can be viewed diagonally from above is used. In other words, display devices (display tubes) are increasingly being installed with the tube axis tilted.However, in the case of color display tubes, the tube axis is tilted. , which is not convenient in terms of its color purity and white unevenness characteristics.

い。Therefore, when viewing the display tube screen upright, the effective surface shape of the display tube cannot be seen in an accurate symmetrical shape due to the relationship between the eye position, the display tube's curved surface radius, and the refractive index. ``The visibility of the screen is a big problem for spray viewers. Particularly in the case of graphic displays, a problem arises in that the display viewer is unable to obtain accurate information due to optical illusions or the like. That is, when a display viewer views the graphic effective surface shape expressed on the display from diagonally above, he/she perceives the effective surface shape 2 shown in FIG. 2. Needless to say, this problem becomes even more serious when the display is used to display graphical processing such as CAD.

本発明の目的は、ディスプレイ観察者が表示有効面形状

供することにある。An object of the present invention is to provide a high-definition color display tube that can prevent a display viewer from being unable to accurately grasp the display contents due to the illusion caused by the background ζ such as the shape of the effective display surface, and which can obtain accurate display information. It is about providing.

察者は対称な形状さ認識することができる。To achieve this purpose, conversely, when a display viewer is given a different real image, in this case an asymmetric effective surface shape, it may be made to be able to perceive this as a symmetric effective surface shape. The relative position of the display viewer to the display surface, i.e. the height of the eyes, the direction of the eyes, etc.
Assuming that the display is in a constant position, if the effective surface of a certain asymmetrical shape is set in advance, the display viewer can recognize the symmetrical shape.

等の問題を避けることができる。Since R2<R,l is set in this way, the effective surface of the display can be seen by the display viewer as a vertically symmetrical shape as shown in Figure 1, and therefore graphic information that depends on the shape of the effective surface is Problems such as illusions can be avoided.

壁であることは言うまでもない。In the present invention, only measures have been mentioned in which the shape of the effective surface of the display tube is made asymmetric so that the display viewer can perceive it as symmetrical. Needless to say, it would be even more perfect if it were displayed in a curved line and electrically corrected so that the display viewer perceives it as a straight line.
