Description

Hidden reading material and display device TECHNICAL FIELD

The present invention relates to the technical field of printing and optoelectronic display, and in particular to a hidden note reader and a display device for reading the hidden note.

Background technique

Existing printed books, especially texts in a certain language, constitute the text, and there are corresponding foreign language readings printed with corresponding annotation symbols, such as English-Chinese comparative readings. The interpretation of English text symbols can be seen at a glance, and it is easy for readers to develop a better understanding of Chinese. Dependency. In view of this shortcoming, there is a kind of bar code which is one of the coding symbols that can be easily read by a machine is used as a comment symbol to be printed next to an English word, which solves this problem very well. However, the disadvantage is that the bar code has certain damage to the original layout effect.

The object of the present invention is to provide a printed foreign language reading book with invisible annotation symbols, which can make the reader not dependent on the interpretation and can maintain a good layout effect.

The inscription in the foreign language reading of the present invention can be read by means of a corresponding inscription display device, especially a display device with an ultraviolet light source.

At present, the portable violet light on the market is mostly used to check the authenticity of banknotes and financial bills. The ultraviolet light emitted by its ultraviolet light source can stimulate the pattern or text printed with fluorescent ink on the paper surface to emit visible light. Existing types of violet lamps have their lamp tubes exposed. Under the action of external visible light, the contrast between text and paper is reduced, and the difficulty of identification is increased. At the same time, the ultraviolet light emitted by the lamp can also damage the eyes. For those who are occasionally used for fluorescent ticket inspections, the problem is not large. However, if it is frequently used for reading for a long time, it will cause eye diseases. For example, short-wave ultraviolet light at 254 nanometers can cause diseases such as conjunctivitis, keratitis, and rainbow inflammation in the human eye.

Therefore, another object of the present invention is to provide an annotated display device, which can make the paper surface and the graphic part show a stronger contrast under ultraviolet light, so that readers of annotated foreign language reading materials can easily add the annotated text. Identifies and does not irradiate the human eye with UV rays. Brief description of the invention

Best Mode of the Invention

Example one

Please refer to FIG. 1 first, which shows the general position of the annotation symbol 1 in this embodiment in the reading article. In this embodiment, a colorless fluorescent ink made of a yttrium-based complex is used. The Chinese interpretation is compiled into a barcode lb by a computer or a smart terminal printer and printed next to the corresponding English word. In this way, you can't see the interpretation and do not affect the layout. When reading and using, under the condition of sufficient intensity of ultraviolet light, bright and dark stripes can be displayed, and then scanned and reflected by the laser of the existing barcode reader, and then read the information to the decoder, and digitize the width and interval of the stripes. Translated into data, the computer responds to the original text according to the programmed program, so that readers get the interpretation content. Of course, you can also use green fluorescent ink to print on green paper or red ink to print on red paper, as long as the hue of the two is similar after printing. In addition, in this example, colorless fluorescent ink can also be used to directly print the phonetic symbols and Chinese characters la. Under ultraviolet light, the reader can see them at a glance or use the existing optical text reading device to scan the input to give a definition. . In addition, in the space where the kerning of the English language is illustrated, a foreign language mother can also be printed as the polysemous discrete code lc. For example, Learned has three definitions: "a", learned; "b", academic; "c", learned. The letter "C" is printed with colorless fluorescent ink. Scanned alphabetic electronic dictionaries with ultra-violet light can be used for accurate interpretation.

Specifically, according to this embodiment, for example, a colorless fluorescent ink can be used to reduce the text symbols in the interpretation part to a size (about 0.8 mm) which is hard to be seen by the naked eye and printed on paper. Because the font is small and the ink is colorless, it is difficult to see under natural light. Under UV light, the ink develops color. When reading, use magnification with UV light Mirror (about 5 times) Easy to read handwriting.

Example two

In this embodiment, Chinese-simplified Chinese characters or barcodes are printed with a colorless compound of bis- (2 ', 4'-dinitrobenzyl) -pyridine as a photosensitive ink. When reading, blue Chinese characters appear under strong visible light conditions. , Or the stripe can be interpreted (voice or graphic) through a text scanner or barcode reader as in the above example.

Example three

In this embodiment, a thermo-varying ink is used to disperse pyrogallol in polyvinyl butyral to print the above-mentioned Chinese characters or barcodes. Under the condition of infrared heating, blue and black fonts can be displayed for reading or stripes can be displayed for machine reading.

Embodiment 4

Instead of ink (referring to display materials), directly use a printing machine (such as letterpress printing press or high pressure flatbed vertical press) to affix the annotation symbol 1 on the paper surface or use ink and paper to color the substance. Hate affinity differences to verify the interpretation. For example, use a colorless or white water-repellent ink (if you add a water-resistant alkyd resin binder, wax auxiliaries, vaseline, etc. to make it more water-repellent), the annotation symbol 1 is printed on itself to be hydrophilic White paper (also treated with inorganic acid salts or sodium carboxymethyl cellulose to enhance its hydrophilicity). For official reading, just swipe it with a highlighter or an ordinary ink pen to display it.

Example 5

In this embodiment, the coloring material is wrapped in an isolation carrier as a medium, and the surface of the isolation carrier is made into a color similar to the printing paper for printing the annotation symbol 1.

For example, using microcapsules containing colorants (prepared from polymer compounds such as vinyl alcohol through polymerization, microporosity, or spray capsule solidification, using mechanical pressure, friction pressure, hot melting, and solvents including water during use) Dissolution causes the capsular membrane to rupture, thereby releasing the contents of the sac) as an ink for pigment printing. The red ink is made into a white (or any color) microcapsule as a white color mixed with a colorless binder to make a white ink, and a comment symbol 1 is printed on a white paper of similar color. When reading, as long as rubbing with your fingers, the microcapsules will be broken to release the red ink, that is, the interpretation of the red writing on the white paper. Example Six

Using pyromellitic dianhydride as the ink, print note symbol 1 on the paper, and then immerse the paper sheet in an aqueous solution of 8% chlorinated starch at a temperature of 27-65 ° C, then remove the paper sheet with The hot air dries it. In this way, the annotation symbol 1 is partially cured in the paper and does not appear to be transparent, or the ink (such as barium white) that has hiding power against light (including visible light) is printed on the paper or paper back, usually nothing can be seen. The definition can be found at any time.

Example Seven

In this embodiment, the paper is printed with a light blue color. This paper can be replaced by air in the fiber when it encounters water or a permeable substance such as engine oil or ethanol, so that the light becomes transparent without being refracted. Use the ink that has a hue or gloss contrast with light blue paper, such as dark brown black ink, to reversely print the glyph of the comment symbol in a mirror-symmetrical form (both direct printing or reverse white printing) on the back of the paper, corresponding to the front of the paper The text of the text article is printed at the comment symbol. The reader only needs to use a pen filled with water or oil or ethanol to pass under the relevant words, that is, the paper will become transparent and the brown and black handwriting of the comment symbol will be exposed.

In the following, several preferred embodiments of a hidden display device for a fluorescent hidden reading book in the above embodiment of the present invention will be described in detail with reference to FIGS. 2, 3, and 4.

Please refer to FIG. 2 first. The hidden display device according to the present invention has a light shield 1 made of a streamlined cylinder made of opaque plastic. Visible light cannot be transmitted under normal reading conditions. When the transparent window 3 on the bottom is close to the paper surface, a dark room with weak internal light is formed. At this time, the touch switch 7 of this embodiment is turned on by the power source 5 due to the hand holding, and the ring-shaped ultraviolet light source 4 is turned on to emit light. The graphics printed by fluorescent ink under ultraviolet light in the dark room make the contrast significant because the influence of visible light is basically eliminated. The hood 1 shown in the figure has a concave reflective surface 2 made of polished aluminum (or gold or silver) flakes, which has a good effect of reflecting ultraviolet light (also can be plated with oxide, fluorine on the base material) (Such as compounds, sulfides, etc.), it can focus the ultraviolet light on the specified graphics and enhance the contrast effect. In addition, in this embodiment, a magnifying glass is installed at the top observation window 6 and the bottom transparent window 3 of the light hood 1, and the minute graphic details can be clearly displayed after being enlarged. This makes it easier for users to identify. The magnifying glass of the transparent window 3 in this embodiment is made of ultraviolet-transmitting quartz; the lamp as the ultraviolet light source 4 The tube material can be made of, for example, model ZWB ₂ (former model of China's Fifth Ministry of Machinery Industry) or QB ₂₄ (corresponding model in Japan is BG-12), or nickel-oxide ultra-violet black light glass. The above materials can absorb the light waves of non-excited fluorescent inks including visible light (thereby substantially eliminating the visible part of the light source 4 and enhancing the contrast, allowing only limited-wavelength ultraviolet light to pass through, and entering the paper surface to excite the fluorescent ink to emit visible light and pass upward The magnifying glass through the observation window 6 allows the reader to see the picture clearly. At the same time, some ultraviolet light is reflected by the paper and also reaches the magnifying glass on the observation window 6. The type of lens material is JB ₉ and JB _510. And WB _38. Or model TB is made of violet filter glass, because it is reflective or absorbent to ultraviolet light (but transparent to visible light), it plays a role in blocking the passage of ultraviolet light (in order to strengthen the violet light, the viewing window 6 It is best to make it with an interference glass, which allows visible light to pass, but reflects back to ultraviolet light, excites the fluorescent ink again, and enhances the contrast) to achieve the purpose of no radiation.

FIG. 2 shows another embodiment of the device, in which the hood 1 and the reflective surface 2 are both composed of the same light-colored plastic conical surface; a magnifying glass is not installed at the transparent window 3, and only the observation window A magnifying glass (also made of UV-blocking filter) is installed at 6 places; a dry cell is used as the power source 5 of the UV light source 4 and at the same time as a handle; a push button switch 7 is mounted on the base and is pressed when it contacts the paper surface It opens immediately. The use of this device is the same as the above embodiment, so it will not be described again.

Fig. 3 shows still another embodiment of the device, wherein the hood 1 is made of a rectangular plastic box; the ultraviolet light source 4 is made of a "U" -shaped tube, and a single slit in the middle can reveal a single line of text. The transparent window 3 and the observation window 6 are not equipped with a magnifying glass, and only a parallel flat glass is installed at the observation window 6 as a filter for blocking ultraviolet rays directly. This kind of glass is ordinary soda-lime glass. If the content of iron oxide (Fe ₂ 0 ₃ ) and titanium oxide (Ti 0 ₂ ) is increased, it will hardly transmit ultraviolet light.

Obviously, the specific application of the hidden display device of the present invention is not limited to the above embodiments. For example, the above-mentioned filter can be made of glass or transparent plastic (also can absorb ultraviolet light); it can be used alone or in addition to a magnifying glass, or it can be coated with a layer or Multi-layered for use.

The invention enhances the condition of ultraviolet light by providing a dark room with a reflecting surface and a magnifying glass. The ability to identify the details of fluorescent graphics is convenient for users or interpreters to see the graphics more easily. At the same time, the use of a filter as a window material eliminates damage to the human eye caused by ultraviolet radiation.

In addition, the specific application of the implicit reading material of the present invention is not limited to the above embodiments. For example, Japanese and French comparison reading materials, Chinese and Pinyin comparison reading materials, Chinese characters and minority ethnic text comparison reading materials can also be produced. It can also be printed with other managerial inks. As another example, the foreign language and its unique interpretation code symbol can also be printed with the ink added with a ferromagnetic substance, and the magnetic signal is converted into the unique interpretation of the foreign language vocabulary by a scanning electronic dictionary when in use.

The present invention directly displays the annotation symbols through various color and shape changes on the surface of the printed reading materials, maintains a good layout of the foreign language reading materials, and can help foreign language readers to learn foreign languages better through machine pronunciation or graphic display, and has processing And the use cost is low, and the advantages of very fast verification and interpretation can solve the problems that have been plagued by foreign language readers.
