Voici quelques idées fausses communes sur les points forts de l'écran nocturne
1. La division de l'éclairage et de la luminosité
Actuellement, la luminosité élevée, la faible consommation d'énergie et le contraste élevé sont tous poursuivis dans l'industrie de l'affichage à cristal liquide à haute luminosité (LCD). Par conséquent, certains hommes d'affaires ne se concentrent pas sur la recherche scientifique et l'innovation, mais sur le concept et les instruments de test.
Tout d’abord sur l’instrument :
A. Testeur de luminance professionnel/luminomètre ordinaire (les marchands utilisent les données testées par le luminomètre ordinaire pour remplacer les données du testeur de luminance professionnel, mauvais!)
B. Utilisez des instruments professionnels pour remplacer la valeur de luminosité par la valeur d'éclairage.
C. les instruments professionnels ne sont pas plus positifs que la normale.
D. Ne pas effectuer d'essai de contraste et d'uniformité de la source lumineuse
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, et la valeur d'éclairage à une distance de 5m de la source lumineuse est: 1200Lm/157 m2 = 7,64Lux. Les produits plus lumineux ne sont pas nécessairement de meilleurs produits, l'écran d'affichage trop lumineux se sent souvent mal à l'aise, d'une part, facile à causer de la fatigue visuelle, mais aussi pour réduire le contraste entre noir et blanc pur, affectant la performance des niveaux de couleur et de gris. Alors augmenter la luminosité de l'écran, mais aussi améliorer son contraste, sinon tout l'écran apparaîtra phénomène blanc. L'uniformité de la luminosité est également très importante. Que la luminosité soit uniforme ou non est étroitement liée à la quantité et à la configuration du rétroéclairage et du réflecteur. La haute qualitéécran LCD 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 panneau LCD 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 LCD haute luminosité 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, Affichage LCD 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.
