Description

Appearance discoloration apparatus of TV {FRAME COLOR CHANGING APPARATUS FOR TELEVISION}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for discoloring appearance of a television, and in particular, an electrochromic device made of an organic material whose color changes according to the intensity of an electric signal is applied to the appearance frame of a television, and then to a user's selection or predetermined conditions. The present invention relates to an apparatus for discoloring the appearance of a television, which is configured to apply a different voltage to the electrochromic element to change the fixed appearance of the television to satisfy the aesthetic satisfaction of the user.

Television is now a very common home appliance, and the appearance is more a purchase factor than a performance consideration. As TVs of various sizes and performances have been developed and distributed, the difference in the performance of TVs is not so different from one manufacturer to another, and the sales volume has been influenced by more individual appearance and beautiful appearance.

For a more personal and beautiful appearance, it is not enough to simply modify the design, and technical support is needed to support it.For the sharpness of the appearance, a control board design technique of a smaller size is required, and a smaller display unit is required. Design skills are required, and various design changes may be required for external beautiful control panels.

However, even when producing a product that emphasizes these design efforts and design features, the consumer's preferences are constantly changing, so the conventional products that maintain a fixed appearance are easily tired. In particular, in the case of color, it is well known that color balance with an installation site desired by a user may be the biggest selection condition, regardless of the performance of a TV. Therefore, when the user changes the place or the environment while using the product, the color of the TV becomes a problem, and the user may want to replace it.

If it is designed to replace the appearance of the television in order to satisfy a variety of users, it is not preferable in terms of the product management of the manufacturer or the need for more replacement efforts of the user.

In addition, if a manufacturer releases a variety of models with different colors for products of the same function according to consumers' preferences, additional costs are incurred in terms of management and development of the product, which ultimately burdens consumers or developers.

Therefore, if it is possible to provide a television appearance that varies variably according to the user's choice or predetermined conditions without additional efforts, it will be possible to satisfy the needs of consumers for a relatively long time.

As described above, since the conventional television appearance is a major factor of purchase, it is provided to the consumer by having the same product family having various designs and colors, but this causes an increase in cost in terms of development, and the consumer also has a choice of design and color. There was a problem that it is difficult to maintain the satisfaction for the product appearance for a long time because the product must be used fixedly until the end of the life of the product.

In view of the above problems, the present invention applies an electrochromic device that can be deformed according to a change in voltage to a part or all of the TV exterior, and the TV exterior color by the voltage determined by the user's selection or automatic selection according to a predetermined condition. It is an object of the present invention to provide an apparatus for discoloring the appearance of a television which is used to vary the display.

The present invention for achieving the above object, the frame structure forming the television appearance; An electrochromic device in which discoloration occurs according to a voltage applied to a part of the surface of the frame structure; A transparent protective layer for protecting the electrochromic element; And a power supply unit for applying a predetermined voltage to the electrochromic device according to an external control signal.

The electrochromic device is configured of a double straight type or a single straight type, and the color is determined when the basic color and the voltage are applied according to the type of the electrochromic layer used.

It will be described in detail with reference to the accompanying drawings of the present invention as described above.

First, it is to be noted that the present invention allows electromorphic devices, which are electrochromic devices, to be generally applied to a fixed television exterior, and to vary the appearance by varying them.

Figure 1 shows the change of the general color change pigment, when the external stimulus is applied to the color change pigment of "A" color, it is shown that the color change to "B" according to the degree of the external stimulus applied. The types of external stimuli to be applied include light, electrons, heat, and solvents. Accordingly, the types of color changeable dyes are also divided into photochromic dyes, electrochromic dyes, thermochromic dyes, and solvent color changeable dyes. You lose.

Among these various pigments, there is an electrochromic dye which can be simply changed into a desired color. This is characterized by the change of absorption wavelength or absorption rate due to oxidation and reduction reaction, and the color change or the color shade of the color change. ElectroChromic Device (ECD) can be used in a large area. In practical terms, there is practicality. In addition, since the power consumption is very low, it can be used without any great burden.

There are two general types of ECD structures: Double Substrate Type and Single Substrate Type. The Double Straight type has electrodes and electrochromic layers (WO ₃ , V ₂ O) on one substrate. ₅ or IrOx), an electrode and a counter electrode layer (NiO, Nb ₂ O ₅ , CeTiO _2, etc.) are formed on another substrate, and then an organic electrolyte is inserted between the electrochromic layer and the counter electrode. It is structured to join afterwards. In addition, the single substrate type has a structure of an electrode, an electrochromic layer, a solid electrolyte layer (Ta ₂ O5, ZrO ₂ , Li ₃ N, LiNbO ₃ ), an opposite electrode, and an upper electrode by using a thin film deposition method on a glass substrate. It is.

The driving mechanism of the general ECD is that color is applied or discolored by the electrochemical reaction caused by the movement of fluid ions (Li ⁺ , or H) through the electrolyte between the electrochromic layer and the counter electrode when a voltage is applied to both electrodes. (Coloring or Bleaching) will occur.

In the present invention, after applying the general ECD formed in the above-described manner to at least a part of the appearance frame of the television, the ECD is discolored by the automatic selection color according to the user's selection or its own criteria. Inorganic crystals used in the early days are very expensive because they are not easy to manufacture, and in the present invention, by controlling the conjugate length, the absorption wavelength of visible light can be adjusted according to the voltage, and an organic material having low manufacturing cost and high physical safety is selected. It is preferable to use it as a chromic layer.

Figure 2 shows an example of the manufacturing process of the ECD applied to the present invention, a process perspective view for producing the above-mentioned single substrate type ECD.

First, a glass substrate (ITO glass) 1 having a transparent Indium Tin Oxide (ITO) electrode is prepared (FIG. 2A), and an electrochromic layer is formed on the ITO electrode of the prepared glass substrate 1 by spin coating. 2) (FIG. 2B). Next, a polyester thin film 3 is formed with a solid electrolyte layer thereon (FIG. 2C), and an ITO glass substrate 4 having a counter electrode and an upper ITO electrode formed thereon is formed thereon. Now, when the voltage is applied to the transparent ITO electrodes formed on the glass substrates 1 and 4, the color of the electrochromic layer 2 is changed.

For example, if the electrochromic layer 2 is C _14, it remains red when no voltage is applied, and then turns gray when a positive voltage is applied.

FIG. 3 is a simplified connection diagram showing a structure in which the above-described ECD is applied to a part of a television frame. As shown in FIG. 3, the ECD 20 is applied to the frame layer 10 and a transparent layer is provided to protect the ECD 20. The protective layer 30 is formed on the upper side. In order to operate this, it is necessary to modify the magnitude of the voltage supplied by the variable power supply unit 40, which can be achieved by using very simple hardware.

For example, the ECD 20 can be changed to a desired color by digitally-analog converting a digital signal provided from a control unit of a television and then providing it to an appropriate driving unit to have sufficient power. Of course, a variety of methods (eg, pulse width modulation, etc.) can generate precise analog voltages, and the present invention encompasses all of these methods.

In addition, it is noted that the ECD 20 may overlap various ECDs to express more colors, and an independent variable power supply unit may be applied to each ECD. In addition, since the color tone changes, it is possible to diversify the color change by applying an appropriate color to the basic frame and adding an ECD to the upper part.

The color of the BCD can be maintained after the user selects a desired color and can also be automatically changed by the user's selection. The automatic change may be provided by changing the color according to the brightness of the screen of the TV, changing the color according to the external temperature (cool when it is hot, warm when it is cold), changing the picture according to the external brightness, and changing the color according to the volume. Can be.

In other words, the user can change the exterior color of the TV to the color of their choice to satisfy their preferences, and if the surrounding environment changes, the exterior color of the TV can be changed to a new color for color harmony, Significant effects can be obtained.

In addition, the dynamic appearance color changing function can be operated according to the user's selection, so that the exterior color of the TV can be dynamically changed according to the external situation or the TV's own situation.

FIG. 4 is an embodiment of the present invention. In the illustrated embodiment, the present invention is applied to the exterior display unit 130 surrounding the screen display unit 100, the control panel unit 120, and the sound output unit 110. In addition, the present invention is applied to the central region of the control panel 120. This can provide a blue accent color in addition to the basic color, the color can be changed according to the user's selection or predetermined conditions.

As described above, the apparatus for discoloring appearance of a television according to the present invention applies an electrochromic element discolored by a change in voltage to a part or all of the appearance of the television and discolors according to a user's selection or a predetermined condition. In addition to providing a variety of TV exterior color according to the TV appearance color is dynamically changed by a variety of external stimulation or TV conditions to eliminate boredom and increase the visual immersion, as a result of the effect that can stimulate the user's desire to buy have.
