本發明係一種螢幕裝置,特別是一種具有螢幕防拍及隱密保健眼睛功能之螢幕裝置。 The present invention is a screen device, in particular a screen device with the functions of screen anti-photographing and secretive health care.
世界各國在全球化發展與數位科技廣泛運用的鉅大影響下,洩露或侵害營業秘密的風險已大幅增加,而營業秘密一旦受到侵害,即無法回復,不但會蒙受重大經濟損失,重挫國家的產業競爭力,更會危及國家的經濟命脈,目前世界各國莫不竭盡最大手段,進行保護相關的營業秘密,而「商業性營業秘密」對於貿易市場影響甚鉅,更是其中最值得保護的標的。 Under the tremendous influence of globalization and the widespread use of digital technology, the risk of leaking or infringing on trade secrets has increased significantly in countries around the world. Once trade secrets are infringed, they cannot be recovered. Not only will they suffer heavy economic losses, but also the country’s industry. Competitiveness will also endanger the country’s economic lifeline. At present, countries in the world do their utmost to protect related trade secrets. “Commercial trade secrets” have a huge impact on the trade market and are the most worthy of protection among them.
而所謂的「商業性營業秘密」,主要包括企業的人事管理,商品售價,客戶名單,交易底價,進貨成本,經銷據點,成本分析,財務經營等與經營管理相關的資訊,而前述的資訊多數具備秘密性,且無法輕易從公開管道可以得知,故 而需要更高的保護手段。 The so-called "commercial business secrets" mainly include enterprise personnel management, commodity prices, customer lists, transaction reserve prices, purchase costs, distribution locations, cost analysis, financial operations and other information related to business management, and the aforementioned information Most of them are secret and cannot be easily known from public channels, so And need higher protection means.
而近年來,由於科技產業的高度競爭,除了高度面臨科技業界的高薪挖角跳槽,更導致有心人士想盡辦法竊取公司的「商業性營業秘密」,將原公司的「商業性營業秘密」帶往新公司或是自行攜出使用。在各式的竊取過程中,除了可藉由公司電腦,以個人手機,隨身碟進行竊取公司的營業秘密外,又以直接偷拍電腦螢幕的方式最為普遍也最為簡便快速,此時,「商業性營業秘密」也因此遺失。證諸實際法院判例,有跨國科技公司確實有離職員工,以自用手機偷拍原公司電腦螢幕畫面,達到竊取公司的「商業性營業秘密」不法目的。 In recent years, due to the high level of competition in the technology industry, in addition to facing high-paying job-hopping in the technology industry, it has also led to those interested in trying their best to steal the company’s "commercial business secrets" and bring the original company’s "commercial business secrets" to The new company or bring it out for use. In the various theft processes, in addition to stealing company business secrets from company computers, personal mobile phones, and flash drives, it is also the most common and the easiest and fastest way to directly take pictures of computer screens. At this time, "commercial "Trade Secrets" are also lost. As evidenced by actual court cases, some multinational technology companies do have former employees who used their mobile phones to secretly take pictures of the original company’s computer screens to achieve the illegal purpose of stealing the company’s "commercial business secrets."
而目前可作為攝影鏡頭偷拍的器材以相機拍攝電腦螢幕畫面,或是以攝影機予以側錄電腦螢幕畫面的方式較為普遍採用,更或是以自用手機拍攝即可簡單完成,故而尚無積極有效可以防止攝影鏡頭偷拍電腦螢幕畫面的解決方式或是遏止手段。 At present, it can be used as a camera for sneak shots. It is more commonly used to capture computer screen images with a camera, or to record computer screen images with a camera, or it can be simply done by shooting with a mobile phone, so there is no active and effective method.

Figure 3B shows the interference diagram displayed by the
故而,當眼睛注視螢幕時,會因為視覺暫留原理,會看到如第3A圖所顯示,亦即看到原有螢幕所顯示的圖示,也就是一般正常的螢幕;但當看到如本發明一種具有螢幕防拍及隱密保健眼睛功能之螢幕裝置時,會看到如第3B圖所顯示,即經過狹縫干涉後,所顯示的干涉圖示,即產生繞射圖形在螢光幕上。亦即,當以手機拍攝螢幕時,就會產生一條一條的條狀帶(banding)圖形,完全無法將機密訊息攝入,而達到保密的效果。 Therefore, when the eyes are looking at the screen, due to the principle of persistence of vision, you will see the icon shown in Figure 3A, that is, you can see the icon displayed on the original screen, which is a normal screen; but when you see it like When a screen device of the present invention has the functions of screen anti-photographing and concealed eye care, you will see the interference pattern displayed as shown in Figure 3B, that is, after the interference of the slits, the diffraction pattern is generated in the fluorescent light. On the curtain. That is, when the screen is shot with a mobile phone, a banding pattern will be generated, which makes it impossible to take in confidential information at all, and achieves the effect of confidentiality.
通常手機內所設的電荷耦合元件(CCD)系統,可進行光線的感應,而目前手機的抗條狀(anti-banding)功能亦對50赫茲(Hz)和60赫茲的閃爍頻率有效(即手機可進行補償,即使拍攝螢幕,手機並不會顯示條狀帶)。甚且,本發明於進行隱密保健的670奈米±50奈米附近的波段,以及於780奈米±60奈米附近的波段,可以避開50赫茲(Hz)-60赫茲抗反條狀帶(anti-banding)的補償操作頻率,此時,光源的操作頻率可以是以直流電(DC)或大於60赫茲而進行操作,換句話說,如當該發光體之(投影)光源的操作頻率大於60赫茲時,即可產生條狀帶,而具有產生螢幕防拍以及眼睛保健的效果。 Generally, the charge-coupled device (CCD) system installed in mobile phones can sense light, and the current anti-banding function of mobile phones is also effective for flicker frequencies of 50 Hz and 60 Hz (that is, mobile phones). It can be compensated, even if the screen is taken, the phone will not display the strips). Moreover, the present invention can avoid the 50 Hz (Hz)-60 Hz anti-retro stripe in the band around 670nm±50nm for secret health care and the band around 780nm±60nm. With (anti-banding) compensation operating frequency, at this time, the operating frequency of the light source can be operated with direct current (DC) or greater than 60 Hz, in other words, when the operating frequency of the (projection) light source of the luminous body When it is greater than 60 Hz, a strip can be produced, which has the effect of screen anti-shooting and eye care.
本發明之一種具有螢幕防拍及隱密保健眼睛功能之螢幕裝置的優勢,其防拍保健的該發光體之(投影)光源為670奈米±50奈米波段,以及光源為780奈米±60奈米波段,而其中光源的操作頻率要避開50赫茲至60赫茲,故不會被手機的 抗條狀所補償掉,而產生繞射明暗條狀排列,甚而具有產生螢幕防拍以及眼睛保健的效果。 The present invention has the advantages of a screen device with functions of anti-photographing on the screen and protecting eyes in secret. The light source (projection) of the luminous body for anti-photographing and health care is 670nm±50nm waveband, and the light source is 780nm± The 60-nanometer band, and the operating frequency of the light source must avoid 50 Hz to 60 Hz, so it will not be affected by mobile phones. The anti-stripe is compensated, and the diffractive light and dark strips are arranged, which even has the effects of screen anti-shooting and eye care.
由於一般人類的眼睛可以覺察到閃爍頻率為50赫茲以下的光源閃爍,相對地,手機的快門(CCD)對於閃爍頻率高於80赫茲都可以反應,故而,當使用控制紅(R)色,綠(G)色,藍(B)色三原色的亮度,以及具有開關時間的發光二極體(LED)時,故可使得手機於攝影時,產生條狀帶(banding),亦即產生猶如是繞射圖形的情況,得以保護螢幕防止他人未經准許的拍攝。 Since the general human eyes can perceive the flickering of light sources with a flicker frequency below 50 Hz, the shutter of a mobile phone (CCD) can respond to flicker frequencies higher than 80 Hz. Therefore, when using the control red (R) color, green The brightness of the three primary colors (G) and blue (B), as well as the light emitting diode (LED) with switching time, can cause the mobile phone to produce banding when shooting, that is, it produces as if it is winding. In the case of shooting graphics, the screen can be protected from unauthorized shooting by others.
本發明之一種具有螢幕防拍及隱密保健眼睛功能之螢幕裝置,係透過狹縫光源以防止照相機,攝影機進行攝/錄未經授權的螢幕畫面,特別是以專用狹縫波形閃爍其液晶面板,從而保護螢幕畫面避免相關的資料洩漏,且本發明該投影光源的操作頻率大於60赫茲時,則可產生對眼部的保健功能。 The present invention is a screen device with screen anti-photographing and concealed eye care functions. It uses slit light sources to prevent cameras and cameras from capturing/recording unauthorized screen images, especially flashing its liquid crystal panels with special slit waveforms. Therefore, the screen image is protected from leakage of related data, and when the operating frequency of the projection light source of the present invention is greater than 60 Hz, the eye health function can be produced.
本發明一種具有螢幕防拍及隱密保健眼睛功能之螢幕裝置,係利用在物理學的「相干性」(coherence)原理而成,所謂相干性,係指為了產生顯著的干涉現象,其中波所需具備的性質。而相干性描述波與自己本身,波與其它波之間對於某種內秉物理量的相關性質。當兩個波彼此相互干涉時,因為相位的差異,會造成建設性干涉或破壞性干涉。故而,當產生雙狹縫的兩個波,稱為干射(interference),產生兩個波以上 則為繞射(diffraction)。 The present invention is a screen device with the functions of screen anti-photographing and concealed health care for the eyes. It is based on the principle of "coherence" in physics. The so-called coherence refers to in order to produce significant interference phenomena. Required properties. The coherence describes the correlation properties of a certain internal physical quantity between a wave and itself, and between a wave and other waves. When two waves interfere with each other, because of the difference in phase, it will cause constructive or destructive interference. Therefore, when two waves of a double slit are generated, it is called interference, and more than two waves are generated. It is diffraction (diffraction).
通常在物理學中,相干長度(coherence length)表示的是,相干波(例如電磁波,光也是一種電磁波)保持一定的相干度進行傳播的距離,在全像攝影與通信工程領域是一個重要的概念。當相干波路徑間的差距小於相干長度時,可明顯觀測到干涉現象,而相干長度越長的波,越接近完美的正弦波。 Usually in physics, the coherence length (coherence length) represents the distance that coherent waves (such as electromagnetic waves, light is also a kind of electromagnetic waves) maintain a certain degree of coherence to propagate, which is an important concept in the field of holographic photography and communication engineering. . When the distance between the coherent wave paths is smaller than the coherence length, the interference phenomenon can be clearly observed, and the longer the coherence length of the wave, the closer to the perfect sine wave.
以上所述僅為本發明之較佳實施例而已,並非用以限定本發明之申請專利範圍;凡其它未脫離本發明所揭示之精神下所完成之等效改變或修飾,均應包含在下述之申請專利範圍內。 The above are only the preferred embodiments of the present invention, and are not intended to limit the scope of the patent application of the present invention; all other equivalent changes or modifications completed without departing from the spirit of the present invention should be included in the following Within the scope of the patent application.
