Benefits of technology

[0010] According to this invention as described above, it can not only reduce the conspicuousness of pixel lines with taking a change of a player's game posture into consideration, but also prevent an aperture ratio of a liquid crystal drive element from being lowered due to unnecessarily fine resolution of pixels, thereby reducing a problem that a screen becomes dark and poorly visible.
[0019] In the above-mentioned invention, it is preferable to constitute one pixel by a pair of adjacent pixel units, and to supply information signals for one pixel in the same timing to pixel electrodes for the same color that are contained in a pair of pixel units respectively. In this case, by displaying data for one pixel of existing image data with a pair of pixel electrodes, it becomes possible to make the pitch between pixel units one half of the conventional one without increasing a data amount of the existing image data. Hence, it becomes possible to achieve a fine resolution of pixels with satisfying the above-mentioned relational expression, and consequently, it becomes possible to display effectively the image according to the progress of the game in the gaming machine.

Problems solved by technology

However, in a liquid crystal monitor, there is a problem that, although a pixel also becomes large as an area of the liquid crystal monitor rises, an image becomes coarse as the pixel becomes large, and the resolution of the image is lowered.
On the other hand, there arises a problem that an aperture ratio (a ratio of the gross area of one pixel to an area which a drive element effectively contributes to displaying in a display screen) of the liquid crystal drive element becomes low and the screen becomes dark and poorly visible.

first embodiment

[0031] FIG. 1 is an explanatory diagram schematically showing a display screen of a display device according to a Note that, in this figure, only 4 pixels in 2.times.2 are shown in an enlarged manner.

[0032] As shown in this figure, in the display screen, a plurality of kinds of pixel electrodes R, G, and B that display three colors of R (red), G (green), and B (blue) respectively are arranged in matrix on an x-y plane, and pixel electrodes of the same color are arranged in the y direction and the same pattern is continuously arranged in an x direction to form a stripe. Moreover, in this display screen, a pixel unit is formed by arranging each kind of pixel electrodes R, G, and B, and one pixel is constituted by each pixel unit.

[0033] FIG. 2 shows a concrete configuration of this display screen. As shown in this figure, in the display device concerned, gate lines G1, G2, . . . that are wired in a horizontal direction in this figure (corresponding to the x direction in FIG. 1) and ar...

modified example

[0056] In addition, the value of the pitch P between pixel units is set up in this embodiment so that the above-mentioned formula (1) may be satisfied. Nevertheless, the value of the above-mentioned P may be set so that the pitch P (mm) and distance d (mm) may satisfy the following relationship:

P=tan(.pi. / 180 / 35).times.d / 2.times.(1+.alpha.) (2)

[0057] where the correction value .alpha. is .+-.0.1-0.2.

[0058] Going in detail of this, the distance d under normal use is 300-500 mm as mentioned above. Nevertheless, since a player's game posture changes every player or by a game status, it can be considered that a player approaches a gaming machine to about one half of the assumed distance d. Therefore, since pixels become conspicuous when a player approaches the gaming machine, the assumed distance d is set at one half in this modified example as shown in the above formula (2).

[0059] In addition, a pixel line becomes not conspicuous if the number of stripes is set to 35 or more. Neverthel...

second embodiment

[0062] Next, a second embodiment of this invention will be explained. This embodiment is characterized in that, in the display device explained in the first embodiment mentioned above, an output for one pixel from the information signal driver 10 which is drive control means, and each of pixel electrodes R, G, and B included in a pair of above-mentioned pixel units a and b (hereafter referred to as Ra, Ga, Ba, Rb, Gb, and Bb suitably) are connected in a one-to-one relationship.

[0063] Going in detail, as shown in FIG. 7, in the display device according to this embodiment, similarly to the first embodiment mentioned above, a plurality of kinds of pixel electrodes R, G, and B that display three colors of R (red), G (green), and B (blue) respectively are arranged in matrix on an x-y plane, and pixel electrodes of the same color are arranged in the y direction and the same pattern is continuously arranged in the x direction to form a stripe. Then, in this display screen, pixel units a an...

Abstract

A display device provided in a gaming machine such as a slot machine or a pachinko machine is equipped, wherein a pitch P between pixel units each of which is formed by arranging each kind of a plurality of kinds of pixel electrodes which display predetermined colors respectively, and a distance d from the display device to a player in a normal game posture satisfy the relationship of P<tan(pi / 180 / 35)xd.

Description

FIELD OF THE TECHNOLOGY[0001] This invention relates to a display device which is provided in a gaming machine such as a slot machine or a pachinko machine.DESCRIPTION OF RELATED ART[0002] In recent years, in the market of gaming machines such as slot machines and pachinko machines, images are mentioned as one of important elements which constitute game property. Conventionally, in an image of a gaming machine, it has become a main stream to mount a liquid crystal monitor or a dot display device whose size is seven inches or less. According to a gaming machine provided with such a display device, it becomes possible by displaying an image according to the progress of a game in the gaming machine to display stages of progress of the game clearly, to make a player's expectations arouse, or to direct a winning status effectively.[0003] In the above-mentioned display device and the gaming machine provided with the display device, while it is possible to expect high stage effects as the ...
