[Problem that the idea aims to solve]

However, in such conventional technology, human visual perception of the liquid crystal display device It was assumed that the point was fixed in a certain position range.

0004 The liquid crystal panel is a CRT (Cathode Ra) used in conventional display terminals. The viewing angle is very narrow compared to y Tube), and the viewing angle is usually between 10 degrees and 3 degrees vertically. If the angle exceeds 0 degrees or 45 degrees left or right, good contrast cannot be obtained, and the human perspective It was necessary to adjust the angle appropriately.

[0005] Especially when used at home, the viewpoint position changes greatly from time to time. Specifically, there is a difference in visual angle between the perspective of a person standing up and the perspective of a person lying down. like this In response to rapid changes in perspective, conventional manual LCD display devices It is said that adjusting the angle of the play display section up and down and left and right is extremely difficult and troublesome to operate. I had a problem.

[0006] Therefore, this invention was developed to solve these problems with conventional liquid crystal displays. Orienting the display of the device to any angle vertically or horizontally The present invention provides a liquid crystal display device characterized by having an angle control means that allows The porpose is to do.

[0007] In addition, in conventional liquid crystal display devices, in order to adjust the display angle, corners that require a person to move and operate and are placed out of reach. It was difficult to adjust the temperature. Therefore, the present invention is based on signals sent from an external control device. Therefore, an angle detection means for detecting the direction of transmission and a direction for determining the direction of the display section are provided. The angle can be easily changed even from a distance by using the adjustable angle determining means. The company also provides a liquid crystal display device.

[0008]

[Means to solve the problem]

In order to solve the above problems, the display device of the present invention uses video and video signals as input signals. Drives and controls the liquid crystal panel based on the video signal and synchronization signal from the computer and information processing terminal. A liquid crystal panel module capable of displaying It has a function that allows the angle of the display section to be adjusted vertically and horizontally. In liquid crystal display devices for video and information processing terminals, the display section It has an angle control means that allows it to be oriented in any desired angular direction. Features.

[0009] In addition, the liquid crystal display device can be controlled based on a signal transmitted from an external control device. By having both angle detection means and adjustment angle determination means, it can be easily adjusted even from a remote location. It can be constructed into a liquid crystal display device whose angle can simply be changed.

In addition, the control switch 104 is a button switch capable of four-way input as shown in FIG. It is preferred.

[0014] The display section 100 is supported by a vertical angle adjustment section 101, and further has left and right angle adjustment. A stack supported by the degree adjustment part 102 and attached to the display base part 103 The vertical and horizontal angles can be adjusted by operating the control switch 104. can be adjusted. The specific operation is the block shown in Figure 2 which is the angle control means. According to the diagram.

[0015] The signal from the control switch 104 shown in FIG. Determine the direction and determine the motor to be driven and the rotation direction. In pulse generation circuit 3 A continuous pulse signal is generated depending on the state in which the control switch 104 is pressed. Mo The controller 4 receives the output signal of the direction discrimination circuit 2 and the output pulse of the pulse generation circuit 3. Based on the signal, the motors 5 and 6 to be driven are switched and the direction of rotation is controlled. Ru. Furthermore, limit sensors 7 and 8 limit the amount of rotation. Limit The sensors 7 and 8 are attached to the vertical and horizontal angle adjustment sections, respectively.
