Image converting device for the display of home automation

The present invention relates to an image reversing apparatus and an image reversing method used in a home auto multimedia multifunction display device. More particularly, the image reversing apparatus can be freely rotated about a horizontal axis and a vertical axis by being held by a main body embedded in a wall. The present invention relates to an image reversing apparatus and an image reversing method of a home auto multimedia multifunction display device in which a compensation circuit is incorporated so that an inverted image is equal to the quality of an input image even if it is inverted up and down.

As the house becomes more advanced and the system is automatically controlled by the home network, the residential environment is changing conveniently and comfortably, and it is possible to use not only digital TV but also living information in both directions through digital multimedia.

In the above system, a video image display device, which is a medium for transmitting and receiving information, is the core, and is installed in various places in a house to acquire information, watch TV, respond to visitors, and crime prevention. In addition to houses, offices and hospitals, as well as spaces and environments, it is used for various purposes, and various technologies such as structure or installation method or multi-function and exterior design that incorporate space utilization and interior elements are continuously developed and utilized.

In the conventional example, US Pat. No. 4,814,759, "Flat panel display monitor apparatus," is a wall-mounted monitor for a hospital room, in which vertical axes are fastened to both ends of the left and right sides of the monitor to allow viewing from side to side, and rotate like a double door refrigerator. It has a structure in which both sides are pivoted up and down by the horizontal hinge. However, in the above invention, the vertical axis, which is not used during left and right rotation, is exposed and the appearance is not good, and the signal cable has a problem that the signal cable is weak in noise because the length of the signal cable needs to be twice the width of the monitor.

In addition, the "embedded multi-function TV device" of Korean Patent Registration Nos. 10-0464265 and 10-0489925 has a long hinge support which is fastened to the back of the TV and the main body of the wall in one or two stages so that the TV monitor can be viewed from the left and right. At least half of the horizontal length of the wall must be withdrawn from the structure to be rotated.

Therefore, in order to solve the problem of falling down due to the weight of the TV monitor, a fairly large hinge structure is required, so that when the TV monitor is pulled out of the wall, a long and large hinge support storage groove is formed in two stages. There is a problem in that it is not exposed to appearance and interior, and the electric signal cable is long, making it difficult to process and weak in noise.

In addition, the image needs to be reversed by rotating the monitor up and down. As a conventional technique for realizing this, Japanese Patent Laid-Open No. 02-158436 relates to a monitoring device. A technique of reversing an image by sequentially writing one frame of image data into a frame memory and then outputting the image in reverse order. Since there are many time constraints and high-speed memory must be used, it is disadvantageous in cost and power consumption is increased.

Korean Patent No. 10-0321433 discloses a forward bidirectional shift register composed of a plurality of flip-flops each having an input and an output terminal in a horizontal driving circuit which is a data signal line and a vertical driving circuit which is a gate signal line of a liquid crystal display device. It is a technology to invert the image by selectively driving the forward signal transmission and the reverse signal transmission by using, and to attach to the panel itself when manufacturing the LCD panel. This is available in large quantities, but it is not applicable when a small amount of LCD of a certain size is required and inversion is necessary. LCD panels also have TTL type and LVDS type, making it difficult to apply to all panels. In this case, the image data is reversed using only the bidirectional shift register, and the inverted image data may sometimes differ from the vertical and horizontal synchronization signals of the initial input signal, and the time clock and pulse waveforms. There is a problem that the screen flickers or flickers, and power consumption is increased so that aging of image quality and eye fatigue easily occur.

An object of the present invention is to install a home auto multimedia multi-function display device on the wall and only the video monitor protrudes on the wall or completely embedded, and even if the video monitor is opened to the left or right when the wall portion is stored as it is in the interior, Its design is good and it doesn't need long hinge support, so the signal cable is short, so even if all the electrical and electronic circuit boards are placed in the main body, it is strong against noise so that it is possible to obtain a clean, ultra-slim and clear image quality, and to place the video monitor in 3D position. In order to be able to adjust the angle of view to the appropriate angle and position without limitation, even if installed upside down, left and right, to select the whole screen and the top and bottom and left and right to reverse the image.

In order to achieve the above object, the present invention, the monitor is rotated from side to side and up and down to enable viewing in both the left and right directions, and the signal cable is short, so that less noise is generated, the image compensation is added by adding an inversion compensation circuit when the image is inverted The present invention provides an image reversing apparatus and an image reversing method for a home auto multimedia multifunction display device which have a beautiful appearance by preventing the hinge portion from being exposed to the outside and have high design freedom in interior or design, and which are advantageous for cost and power consumption.

As described above, the home auto multimedia multi-function display device in which the T-shaped biaxial rotation of the horizontal axis and the vertical axis and the image reversal using a double cylindrical cylinder hinge for a predetermined distance linear reciprocation and an image reversing circuit is embedded in the wall. If the video monitor is installed to be protruded or completely embedded in the wall, and the video monitor is opened from side to side, the stored wall part remains as it is, so the interior and design are good and there is no need for a long hinge support. Therefore, even if all the electrical and electronic circuit boards are placed in the main body, it is strong against noise, so it is possible to obtain a clean, ultra-slim and clear image quality, and the video monitor can be realized in three-dimensional position, so that the angle of view can be adjusted to an appropriate angle and position without limitation. Can and landfill video monitor It is a very convenient structure that can be installed upside down and left and right when installing in the corner of the house and corners of the house, and the structure that the video monitor does not collide with the wall surface even when storing, withdrawing or using it in the jaw. It is inexpensive and simple to select the entire screen and only the top, bottom, left and right to compose the image reversal and image reversal compensation circuit, which is advantageous in terms of cost and compensates for the reversal period and phase.

In addition, the front of the video monitor is made of acrylic resin or ABS resin with a touch button or a touch screen plate, and the joint is made of silicone resin or rubber waterproof packing, which is advantageous for waterproofing, and the half mirror is deposited on the back of the touch screen or touch button. There is a mirror function that has the advantage of being an indoor mirror when the power is turned off.

In addition, digital multimedia broadcasting, communication circuit configuration, digital TV, IPTV, radio, telephone, video phone, video telephone, home automation, home shopping, electronic album and home appliances remote control and PIP This feature allows you to talk to visitors while watching TV or multimedia communications.

A first embodiment of a home auto multimedia multifunction display device according to the present invention includes: a main body 1 having a front surface embedded in the same plane as a wall 9; It is installed in the center of the side of the main body 1, the outer cylinder (3a) formed with a circumferential guide groove (2) in the circumferential direction, and is rotatably inserted into the outer cylinder (3a), and inserted into the circumferential guide groove (2) A double cylinder cylinder hinge 6a composed of an inner cylinder 5 in which a stopper protrusion 4a is formed; And a monitor 8 fastened to a vertical shaft 7 installed perpendicular to an end of the inner cylinder 5 and installed to rotate left and right.

In addition, the first embodiment is an embodiment in which the monitor 8 is fixed to the wall 9, that is, is not drawn out forward. Alternatively, the monitor 8 may be pulled forward by a predetermined length from the wall 9 and rotated. In this case, the double cylinder cylinder hinge 6b is characterized. That is, as another 2nd embodiment, the main body 1 embedded in the wall 9; The outer cylinder is installed in the center of the side of the main body 1, the linear guide groove 10 is formed in the longitudinal direction, and the circumferential guide groove 2 is formed in the circumferential direction so as to be connected to the end of the linear guide groove 10 A double cylindrical cylinder 6b consisting of an inner cylinder 5 having a stopper protrusion 4a inserted into the outer cylinder 3b so as to be inserted, withdrawn and rotated into the outer cylinder 3b. ); And a monitor 8 fastened to a vertical shaft 7 installed perpendicular to an end of the inner cylinder 5 and installed to rotate left and right.

In the above, the stopper protrusion 4a interacts with the inversion detection sensor 12 provided on a part of the rotational trajectory of the stopper protrusion 4a, and acts as an element for detecting the vertical rotation of the monitor 8 to invert the image. do.

And the mounting groove 13 is formed in the surface of the inner cylinder 5, The stopper which fits into the said mounting groove 13 is provided in the outer cylinder 3a, 3b, and determines the extraction position of the inner cylinder 5, It is a structure which supports the load of the monitor 8, and determines the rotation position of the inner cylinder 5. As shown in FIG. That is, the stopper may be a ball stopper 14 in the shape of a ball, or a bar spring stopper 15 in the shape of a flat spring.

In addition, in the second embodiment, the inner cylinder 5 is elastically supported by the spring 16 on which one end of the outer cylinder 3b is seated and linearly moved, and is straightened by the locking step 17 fixed to the outer cylinder 3b. A vertical shaft rotation preventing rod 18 is installed in which displacement of the movement is determined; An embossed protrusion 19 is formed at the end of the vertical axis preventive bar 18; A negative seating groove 25 is formed in the vertical axis 7; The monitor 8 is drawn out more than the displaced end of the linear movement of the vertical shaft rotation preventing unit 18 so that the relief projection 19 and the recess seat 25 fall so that the monitor 8 is rotated.

Other embodiments which function as the rotation preventing device of the monitor 8 described above and which control the rotation of the monitor 8 in any case, whether the structure of the monitor 8 is embedded or protruding from the outside, are also possible. That is, in order to prevent the monitor 8 from hitting the wall by simultaneously rotating the double cylindrical cylinder hinges 6a, 6b and the vertical axis 7, which are the horizontal axes, the rotation of the monitor 8 being flipped at a certain angle is prevented. It is a structure that enables rotation that is reversed up and down after it occurs.

In this case, as illustrated in FIGS. 20 to 22, a locking protrusion 26 is formed at an upper portion of the vertical shaft 7, and a protrusion groove 27 is formed at a lower portion of the vertical shaft 7. Then, the cam projection 28 is fixed to the side of the monitor 8 and the projection groove 27 is fastened to the lower portion of the central axis of the vertical shaft (7). The protrusion groove 27 is formed only at a predetermined angle portion of the lower end of the vertical shaft (7). And the engaging groove 29 is fastened to the engaging projection 26 of the upper end of the vertical shaft (7) is formed in the inner cylinder (5) or outer cylinder (6a) (6b). In addition, the spring 16 is provided to give an elastic force to push the vertical shaft (7) downward.

Therefore, when the monitor 8 is turned to the wall surface, the locking projection 26 is inserted in the locking groove 29, and the cam projection 28 is in contact with the outside of the projection groove 27. .

When the monitor 8 is rotated at a predetermined angle about the vertical axis 7, the above state is maintained. Therefore, since the locking protrusion 26 is inserted into the locking groove 29, the monitor 8 is not reversed up and down.

However, when the monitor 8 is completely rotated about the vertical axis 7, and the cam projection 28 fixed to the side of the monitor 8 is inserted into the projection groove 27 formed at the lower part of the vertical axis 7, the vertical axis (7) is pushed downward by the spring 16, the locking projection 26 is removed from the locking groove (29).

Therefore, the monitor 8 can be freely rotated up and down, thereby preventing the monitor 8 from interfering with the wall and being damaged by being prevented from inverting up and down without being completely rotated from side to side.

The monitor 8 may be added with a half mirror function. That is, a half mirror is directly vacuum-deposited with aluminum, nickel, chromium, silver, copper metal or titanium dioxide and silicon dioxide on the rear surface of the glass of the touch screen or the flat surface of the touch button without inserting a separate half mirror plate. It can be implemented as a mirror function.

In other words, the conventional half-mirror technology is a structure that becomes a mirror when the power is turned off to the mobile phone, carnaby, oxyl TV, and the TV when turned on. Its structure is a half mirror plate deposited with a half mirror metal deposition between the touch screen and the LCD, and not only is thick but also increases in weight.

In contrast, the present invention does not insert a half mirror plate between the touch screen or the touch button and the LCD on the front of the LCD monitor, and directly in the rear glass plate of the touch screen, titanium dioxide (TiO 2), silicon dioxide (SiO 2), silver (Ag), and aluminum. The half mirror layer is deposited to form a half mirror by depositing a metal such as (Al) or nickel (Ni).

Therefore, the thickness of the monitor 8 is reduced, material costs are reduced, and it is very convenient to use as a mirror when the TV is turned off.

According to various embodiments as described above, the monitor 8 is converted to various angles and positions, thereby increasing user convenience and utilization.

1 to 5 in which the first embodiment is shown, the main body 1 is embedded so as to have the same plane as the wall 9, so that the main body 1 can be concealed by wallpaper or the like. Therefore, its utilization in the interior interior is very large.

The monitor 8 is provided on only one side of the main body 1 by the double cylindrical cylinder hinge 6a, so that the monitor 8 is not exposed to the external appearance. The monitor 8 is rotated horizontally from side to side by the vertical axis 7, and has a structure of vertically rotating up and down by the double cylinder cylinder 6a.

First, the monitor 8 is in close contact with the wall surface of the main body 1 side as shown in FIGS. 1 and 3, or it is in close contact with the wall 9 opposite to the installation position of the main body 1 as shown in FIG. Therefore, the structure is space-saving, and if necessary, it provides a structure in which the monitor 8 can be rotated left and right or up and down for viewing.

As shown in FIGS. 1, 3, and 5, the horizontal rotation of the monitor 8 is performed by the vertical shaft 7 in which the inner cylinder 5 and the monitor 8 are fastened.

The rotation range of the monitor 8 is determined by the stopper protrusion 4b, whereby the monitor 8 is prevented from interfering with the wall 9. Therefore, the stopper protrusion 4b is formed on the vertical axis 7 as shown in FIG. 9, and the monitor 8 is provided with a structure for stopping the rotation by contacting the stopper protrusion 4b.

As described above, the monitor 8 is freely rotated by the vertical axis 7, and the wiring of the monitor 8 and the main body 1 is connected to the main body 1 through the wiring hole 24 and the inner cylinder 5 shown in FIG. ). Therefore, since the monitor 8 is always rotated by the vertical axis 7 on one side, the length of the wiring is shorter than in the prior art, thereby reducing noise.

Next, the monitor 8 can be rotated up and down by an angle, or can be rotated up and down by 180 degrees for viewing. This is achieved by the double cylindrical cylinder hinge 6a. That is, as shown in FIG. 2, the monitor 8 is rotated while the rotation angle is adjusted by the double cylinder cylinder hinge 6a constituted by the outer cylinder 3a and the inner cylinder 5. The inner cylinder 5 on which the monitor 8 is mounted is inserted into the outer cylinder 3a and rotated. A stopper protrusion 4a protruding outward is formed in the inner cylinder 5, and the stopper protrusion 4a is inserted into and moved in the circumferential guide groove 2 formed along the circumference of the outer cylinder 3a. Rotation is stopped at the end of the groove (2).

The stopper protrusion 4a also serves as a component for generating a signal for detecting that the monitor 8 is rotated by an angle and inverting the image output to the monitor 8. That is, as shown in Fig. 1, Fig. 2 and Fig. 6, the inversion detection sensor 12 is installed on the rotational trajectory of the stopper protrusion 4a to detect the rotation of the monitor 8, thereby inverting the image. To generate a signal. The inversion detection sensor 12 may be implemented in various ways, such as a tact switch method, a light sense method, a magnet method, and a +/- energization method.

The wiring of the monitor 8 and the main body 1 is wired to the inner cylinder 5 through a wiring hole 24 connecting the monitor 8 and the inner cylinder 5, as shown in FIG. Connected.

In the second embodiment, as shown in FIG. 7, the monitor 8 is also embedded with a wall 9 so that the front surface of the monitor 8 is flush with the surface of the wall 9, and the monitor 8 is rotated from side to side. In the case of inverting up and down, the monitor 8 is drawn out. In this case, therefore, the inner cylinder 5 of the double cylindrical cylinder hinge 6b is drawn out to the outside.

That is, as shown in FIGS. 8 and 9, when the monitor 8 is taken out, the stopper protrusion 4b protruding from the inner cylinder 5 is horizontally along the straight guide groove 10 formed in the outer cylinder 3b. Is moved. As a structure for determining the limit of the horizontal movement, the stopper protrusion 4b is made in contact with the end of the linear guide groove 10.

In addition, the monitor 8 must be rotated in a state where complete drawing is made, and the monitor 8 is not rotated in a state where the drawing is not made completely, thereby preventing interference between the monitor 8 and the wall 9. .

In other words, the vertical axis rotation preventing rod 18 and the vertical shaft 7 are fastened in a state in which the vertical axis rotation preventing rod 18 and the vertical shaft 7 are fixed. It is detached and the monitor 8 is freed.

In this way, the vertical axis of rotation prevention guide 18 is moved with the withdrawal of the monitor 8, the projection of the vertical axis of rotation prevention guide 18 is no longer moved by the latching jaw 17 fixed to the outer cylinder (3b). , The monitor 8 continues to be drawn out together with the inner cylinder 5 so that the relief projection 19 formed at the end of the vertical shaft rotation preventing rod 18 and the intaglio seating groove 25 of the vertical shaft 7 are separated, and the monitor 8 ) Rotation is possible.

In addition, there is a toggle device 20 that can be pulled out by pressing the monitor 8 and inserted again. The toggle device 20 is a general structure, and thus a detailed description thereof will be omitted.

The left and right rotation of the monitor 8 is made with respect to the vertical axis 7, and the structure inverted up and down is the same as in the first embodiment.

 The connection structure of the monitor 8 and the inner cylinder 5 may vary as shown in FIG. That is, in FIG. 12 (a), the axial groove 21 penetrating back and forth in one side of the monitor 8 is formed, and the inner cylinder 5 is axially axially stored therein, whereby the rotation angle of the monitor 8 is increased. 12 (b) is a case where the bearing groove 21 is not penetrated but is recessed in one side. In the case of FIG. It is held by the vertical axis | shaft 7 at (5), and the coupler 22 is held by the monitor 8 by the rotating shaft 23 which became horizontal, and is characterized by the large degree of freedom of rotation.

Due to the structural features as described above, the monitor 8 can be rotated in various ways, and has a structure and a method of inverting an image according to the rotation of the monitor 8, which will be described with reference to FIGS. 15 to 17. I would like to.

Fig. 15 is a block diagram showing the construction of an internal circuit for image inversion. A multiplexer control switch 903 for selecting video signals of the TV tuner 901 and the camera 902 and for switching the plurality of image signal lines at the same time; An A / D converter 904 for converting an input video signal to digital; Storage means comprising a plurality of vertical line memories A (906), vertical line memories B (907), horizontal line memories (C 909), and horizontal line memories (D 910) for storing pixel data of vertical and horizontal scanning lines; and; An image inversion detecting sensor (912) for selecting a scanning line requiring image inversion among the horizontal and vertical scanning lines; When the inverted signal of the selected scan line is input, one scan line is divided into odd and even numbers so that the vertical line memory A 906 and the horizontal line memory C 909, which are the odd memory, and the vertical line memory B 907, which are the even memory, are horizontal. While alternately storing in the line memory D 910, and inputting into the vertical line memory A 906 and the horizontal line memory C 909, which are the odd memory units, the vertical line memory B 907, which is the excellent storage unit, which is waiting. ) And the horizontal line memory D 910 and the vertical line memory B 907 and the horizontal line memory D 910 which are the even-numbered memory units, and the vertical line memory A 906 and the horizontal line memory which are the odd memory units. A CPU 908 which performs the operation of inverting the entire image, the left and right or only the top and bottom images by repeating the input of the pixel data stored at C 909 and the output in the reverse order, and performing display control; A timing control circuit section 905 for separating and synchronizing a synchronization signal of an input video signal with a display driver IC; The extracted signal is stored in the vertical line memory A 906 and the horizontal line memory C 909 as the odd memory unit, and the vertical line memory B 907 and the horizontal line memory D 910 as the even memory unit, and the output is inverted. The signal is an inverter 911 which is a phase inverter which converts the timing phase for each scan line again to a reverse phase different from that of the input; And a D / A converter 915 for converting the analog signal through the buffer 914. The CPU 908 not only switches and performs image inversion, but also controls memory, and monitors the correlation between the period of change of the display pattern and the polarity inversion period of the reference data voltage. When the count is determined to be a specific pattern, an image inversion compensation processing function may be included in which a reference voltage having a different polarity inversion period is supplied to control switching of the polarity inversion period arbitrarily.

In the above configuration, when a signal is detected by the image reversing sensor 912, the CPU 908 performs an inversion of the address of the memory for each vertical and horizontal synchronization signal line; A timing conversion step in which an output switch 913 converts the timing of the signal reversed from the CPU 908 to the inverter 911 which is a phase inverter for each line; The buffer 914 stabilizes the output signal and converts the output signal into an analog signal through the D / A converter 915. The buffer 914 is displayed on the video monitor display unit 11.

There are known methods of inverting an image for each screen frame, a method for inverting each scanning line horizontally or vertically, and an method for inverting each display pixel. When a pattern having a specific relationship is displayed, the display screen is severely flickering and shaking, and power consumption is increased.

The image reversal method of the present invention is a method of storing and reversing image data for each line and a method of compensating for the inverted image. A plurality of vertical and horizontal line memories (vertical line memory A 906, vertical line memory B 907, horizontal line memory C 909 and horizontal line memory D 910) for storing pixel data In order to be stored in a plurality of memory units, the data is accessed in a predetermined order, and the stored pixel data of one scan line line is output in the reverse order when inputted.

That is, while the input pixel data of one scan line segment is sequentially input to the vertical line memory A 906, the waiting vertical line memory B 907 simultaneously outputs the previously stored pixel data in the reverse order to output the vertical line memory A ( 906 and the vertical line memory B 907 are repeatedly stored and output alternately.

In this case, in the case of the gate signal which is the vertical line, the pixel data of the odd scan line is stored in the vertical line memory A 906, and the data of the even scan line is stored in the vertical line. In the memory B 907, the pixel data of the horizontal scan line line which is the data signal is similarly processed.

At this time, in order to stabilize the quality of the image quality, the inverting control extracts a horizontal or vertical synchronization signal from the input signal by the timing control circuit 905, and serves as a memory controller to reverse the address of the memory for each extracted line. In addition, the CPU 908 performs a control operation, and the inverted output signal is inverted from the output switch 913 to the inverter 911 which is a phase inverter for each scan line. And an inverted image phase compensation circuit configuration for converting the phase to the buffer 914 to stabilize the image, and converting the analog signal from the D / A converter 915 to the video monitor for display.

The CPU 908 in the image inversion compensation circuit configuration of the present invention not only quickly calculates the image inversion and controls the memory, but also constantly monitors the correlation between the change period of the display pattern and the polarity inversion period of the basic voltage. When the amount of change in the image data is counted and the synchronization between the inversion period of the data voltage and the change period of the specific display pattern is shown in comparison with a predetermined value, the polarity inversion period is arbitrarily switched to increase the brightness of the screen and increase the power consumption. It is characterized in that the execution including the reducing function. At this time, the function role control of the CPU 908 is processed by S / W and utilizes a CPU that is basically entered in the circuit configuration, so a separate CPU is not required.

The image reversal method according to the present invention solves the problem of image flickering or shaking by using an inexpensive memory that can handle the memory capacity of only one scan line line and an existing CPU and compensating the image after inversion, thereby reducing power consumption. It can be reduced and can be easily configured when needed.

FIG. 16 is a flowchart illustrating an embodiment of a process of implementing image inversion according to the home auto multimedia multifunction display device of the present invention.

If the memory for storing the odd-numbered lines is the vertical line memory A 906, the waiting vertical line memory B 907 outputs the previously stored even-numbered data in reverse order and simultaneously inputs and outputs repeatedly. This is a flowchart of operation of implementing image reversal by executing.
