Description

Light Emitting Antenna Display

An embodiment of the present invention relates to a light emitting antenna display.

In general, a display is a device that visualizes and displays information that is intended to inform people, and is currently located in every corner of our daily lives. From now on, it is difficult to find a place where we can find a place where we cannot find anything, such as smartphones, TVs, computer monitors, order / payment kiosks, bus stop information monitors, school's smart blackboards, and large-scale mart advertisement monitors. . Such displays largely include CRTs, projectors, flat panel devices, e-papers, and the like.

In one example, the flat panel device may include LCD, PDP, LED, OLED, and the like.

LCD stands for Liquid Crystal Display and is called a liquid crystal display, and is widely used in computers, TVs, smartphones, and automobile / aircraft speed displays. This is a method in which liquid crystal, which is an intermediate substance between solid and liquid, is injected between two thin glass plates to change the molecular arrangement of the liquid crystal by the voltage difference between the electrodes on the upper and lower glass plates to generate contrast and drive the passive matrix method and active matrix method according to the driving method. There is this. The LCD has the advantages of low power consumption, light weight, and slimness, so it is convenient to carry, but it has the disadvantages that it does not emit light itself, has poor vision and luminance, and has a slow response speed.

PDP stands for Plasma Display Panel and is called a plasma display. A mixed gas (argon, neon, etc.) is inserted between the positive electrodes to display the ultraviolet rays generated during plasma discharge when voltage is applied as an image. Since PDP is a luminous type and can display clearly, it is widely used in OA devices, etc. It has high display quality as well as a fast response speed, high reliability, and long service life. However, high power is required, and the clarity is inferior to that of LCDs.

The LED TV has a direct type that spreads the LED evenly and shoots the light in front, and an edge type that displays the LED by linearly placing the LED in the upper and lower spaces, and it has great advantages in processing speed, power consumption, and life due to the characteristics of semiconductor. Have Although it is expensive, it has emerged as a new large display as LED commercialization and price decline continued.

OLED stands for Organic Light Emitting Diode and is called an organic light emitting diode. OLED is a method of displaying color by using the phenomenon of emitting light while electrons and holes separated by electrical shock recombine in a specific semiconductor material, high brightness, long life of battery, response speed approximately 1000 times faster than LCD, lightweight, thin With its low power, the current thickness is realized up to 1 mm, which is expected as a next-generation flat panel display that replaces liquid crystal. It is a self-light-emitting diode that emits light as current flows between organic materials, and has a passive driving method and an active method.

As shown in FIG. 2, electromagnetic waves (light) may include gamma rays, X-rays, ultraviolet rays, visible rays, infrared rays, microwaves, and radio waves. The light emitting antenna display 100 according to the embodiment of the present invention generates the electromagnetic wave having the frequency band by the oscillator unit 110, and also forms the antenna unit 140 having a size corresponding to the frequency band, thereby Visible light can be generated. Of course, embodiments of the present invention can also generate ultraviolet and infrared rays in the manner described above.

FIG. 3 shows the positions of the three primary color gamuts of CIE RGB and the CIE 1931 xy chromaticity coordinate system.

As shown in FIG. 3, the light emitting antenna display 100 according to an embodiment of the present invention generates an electromagnetic wave having a desired frequency band by the oscillator unit 110 and also has an antenna unit having a size corresponding to the frequency band ( By forming 140), visible light of a desired color can be freely generated in the CIE RGB three-primary color gamut and the CIE 1931 xy chromaticity coordinate system. Accordingly, an embodiment of the present invention can provide a display 100 having superior color expression compared to the prior art.

For example, in the light emitting antenna display 100 according to the embodiment of the present invention, when sufficient energy is pumped to the antenna unit 140, the antenna unit 140 is heated, and accordingly, the antenna unit 140 through a heat radiation process Will emit visible light. As described above, electromagnetic waves have various frequencies such as gamma rays, X-rays, ultraviolet rays, visible rays, infrared rays, microwaves, and radio waves. For example, red visible rays emitted from the antenna unit 140 are emitted by the Wi-Fi router. It is the same as wireless electromagnetic waves. That is, both are electromagnetic waves. The red visible light only has a higher frequency than the radio electromagnetic wave. Since these two basically have a principle, the frequency of the oscillator unit 110 driving the antenna unit 140 and the size of the antenna unit 140 can be adjusted to cause the antenna unit 140 to emit visible light. . The embodiment of the present invention uses the oscillator unit 110 so that the electrons in the antenna unit 140 perform up / down vibrations (the electric field is formed by the up / down vibrations of the electrons), as described above. Or it can be implemented with an optical circuit.

In general, the wireless antenna of a Wi-Fi router emits wireless electromagnetic waves having a frequency of approximately 2.4 GHz, which corresponds to a wavelength of 12.5 cm. As is well known, the wireless antenna can emit electromagnetic waves most efficiently when its length and the wavelength of the wireless electromagnetic waves are the same or 1/2 or 1/4. Therefore, the wireless antenna of the Wi-Fi router usually has a length of 12.5 cm. On the other hand, the wavelength of blue visible light is approximately 470 nm. Since the size of a general wireless antenna is too large, it cannot emit visible light. Therefore, the size of the antenna must be reduced to match the wavelength of visible light. In addition, the frequency of blue visible light is approximately 640 THz. Usually, the electronic circuit may not operate because the material properties of the electronic component can be changed in this frequency range. Therefore, in the embodiment of the present invention, the oscillator unit 110, the amplifying unit 120, the output adjusting unit 130, etc., may all be implemented as an optical circuit rather than an electronic circuit. Of course, the present invention does not preclude the adoption of electronic circuits, and if there is a suitable material whose characteristics do not change, the above configuration / operation can be implemented even with electronic circuits.

In general, in emitting light using an antenna, the size of the antenna unit 140 must be reduced, and the electrons must be driven at high frequencies. To this end, as an example, the present invention can complete the antenna display 100 by manufacturing the size of the antenna unit 140 on a nano scale and also inducing electromagnetic vibration with incident light through an optical circuit. Here, heat loss may occur when the electron is up / down (vibrated) in the nano-sized antenna unit 140. A laser resonance is similar to this principle. Accordingly, the present invention may further include a heat sink that quickly dissipates heat to the rear side of the antenna unit 140 of the display 100. The heat sink may include a conventional aluminum panel or the like.

As illustrated in FIG. 4, among the light emitting antenna displays 100 according to an embodiment of the present invention, the antenna unit 140 may include patch antennas 151 to 156. In some examples, the patch antenna may be formed by sputtering or plating copper, aluminum, gold, silver, nickel, and palladium on an insulating substrate. In addition, the size of the patch antenna may be formed to a size corresponding to the wavelength of visible light of a desired color. Moreover, the antenna unit 140 has a square solid patch antenna 151, a rhombus patch antenna 152, a circular solid patch antenna 153, and a rectangular solid inside a square of a square line. It may include a patch antenna 154 having an empty space, a patch antenna 155 of a polygonal soli form, and a patch antenna 156 having a circular empty space formed inside a square solid form.

As described above, the size of the antenna unit 140 is provided so that resonance occurs in each wavelength band of RGB, that is, the size is changed according to a desired wavelength band, so that a desired wavelength is obtained by combining the physical size and frequency of the antenna unit 140 It can output the color of, it can be excellent color expression accordingly.
