Hier sind einige häufige Missverständnisse über Nachtbildschirm-Highlights
1. Die Teilung von Beleuchtung und Helligkeit
Derzeit werden hohe Helligkeit, niedriger Stromverbrauch und hoher Kontrast in der Industrie der hohen Helligkeit Flüssigkristallanzeige (LCD) verfolgt. Deshalb konzentrieren sich einige Unternehmer nicht auf wissenschaftliche Forschung und Innovation, sondern auf Konzept und Testinstrumente.
Zunächst zum Instrument:
A. Professioneller Leuchtstoffprüfer / gewöhnlicher Leuchtstoffmesser (Händler verwenden die Daten, die durch gewöhnliche Leuchtstoffmesser getestet wurden, um die Daten des professionellen Leuchtstoffprüfers zu ersetzen, schlecht!)
B. Verwenden Sie professionelle Instrumente, um den Helligkeitswert durch den Beleuchtungswert zu ersetzen.
C. professionelle Instrumente sind nicht positiver als normal.
D. Tut keinen Kontrast- und Lichtquelleneinheitstest
The second is in concept: consumers face some professional terms are indistinguishable, either to see the screen is bright or its brightness or illumination. Intensity (lightness) is a kind of nature color, or have relationship with bright color of the color space of a dimension. In the Lab color space, brightness is defined to reflect the subjective feeling of brightness of human beings. Illuminance is defined as the intensity of light (luminosity) per unit of projected area of any surface in a given direction, viewed from the same direction. The units are feet lambert. The unit is Lux (lx), namely 1m/m2. And the definition of brightness refers to the luminous body (reflective body) surface luminous (reflective) strength of the physical quantity. When human eyes observe the light source from one direction, the ratio between the light intensity in this direction and the light source area "seen" by human eyes is defined as the brightness of the light source unit, that is, the luminous intensity on the unit projected area. The unit of brightness is kendra/square meter (CD /m2). The brightness is the person's perception of the intensity of light. It's a subjective quantity. Unlike brightness, the objective corresponding quantity defined by physics is light intensity. These two quantities are often confused in common everyday language. Illuminance value is affected by the size of the space, length, height, reducing light coefficient, number of lamps, representing the area of the illuminated object, amount of light. To the quantity of illumination has a perceptual knowledge, the following example calculation, a 100 w bulb, the total luminous flux from about 1200 lm, if assumes that the luminous flux evenly distributed on the half spherical surface, is away from the light source 1 m and 5 m of the illuminance values can be obtained according to the following steps: hemisphere with a radius of 1 m area for two PI * 1 ^ 2 = 6.28 m2, is apart from the light source is 1 m of illuminance value is: 1200 lm / 6.28 m2 = 191 lux. Similarly, the hemisphere area with a radius of 5m is: 2 PI ×5^2 = 157 m2, und der Beleuchtungswert in einem Abstand von 5m von der Lichtquelle beträgt: 1200Lm/157 m2 = 7,64Lux. Hellere Produkte sind nicht unbedingt bessere Produkte, der Bildschirm zu hell fühlt sich oft unangenehm an, einerseits leicht visuelle Müdigkeit verursachen, aber auch den Kontrast zwischen reinem Schwarz und Weiß zu verringern, was die Leistung von Farbe und Grau beeinflusst. So erhöhen Sie die Helligkeit des Displays, aber verbessern Sie auch seinen Kontrast, sonst wird das gesamte Display weißes Phänomen erscheinen. Auch die Gleichmäßigkeit der Helligkeit ist sehr wichtig. Ob die Helligkeit gleichmäßig ist oder nicht, hängt eng von der Menge und Konfiguration von Hintergrundbeleuchtung und Reflektor ab. Die hohe QualitätLCD-Bildschirm has uniform brightness, soft and non-glare, and no obvious dark area.
2. Division of LCD screen and LED screen
In highlighting consumers are often met in the LCD-Bildschirm industry merchants said LCD highlighting, LED change is highlighted, it is easy to mistake a consumer to currently on the market of LED dot matrix display screen, which we call LED/LCD system for liquid crystal display, while the latter LED dot matrix display screen is a light emitting diode, the former consists of LCD glass and backlit display device, while the latter is directly displayed by LED lights, it is important to note the highlighted the LCD panel industry of LCD/LED screen is, in fact, according to the backlight naming method and derived, LCD screen (CCFL backlight), LED screen (WLED backlight) LCD screen to highlight is actually the CCFL backlit LCD screen to WLED backlight, LED screen to highlight is the original WLED backlight of the LCD screen to brighten, of course, the highlight screen is not only to change the backlight, more in-depth technical problems need to consult the corresponding Hohe Helligkeit LCD manufacturers.
3. Highlight the original screen and assembly screen
Current global several Large LCD manufacturers only RisingStar, RisingStar, RisingStar, mitsubishi in highlight LCD production, RisingStar only 47/72 inch 2000 nit two Gao Liangbing, said has stopped production, RisingStar 55/65 inch 1000 nit Gao Liangbing, mitsubishi industrial small size, the more the due to highlight the application field of liquid crystal screen environment worse and the demand of the market is not much, LCD-Anzeige the original manufacturer of Gao Liangbing price is quite expensive, is now the highlight LCD screen on the market or in the majority with assembly, and accounts for the absolute market share, So-called highlighting the metal screen assembly is used for the PuLiang LCD screen in the original screen under the condition of invariable appearance and structure to be modified, (easy to mislead the consumer is to highlight the original screen), another kind is under the condition of the original screen structure to be modified (using only the original manufacturer of LCD glass), domestic highlight LCD industry now the highlight LCD screen assembly modification.
