Mobile phones have been an essential element of our daily life, and with the development of the times and the advancement of technology, cell phones have undergone radical changes in the past two decades. From feature phones to smart phones, cell phones have a larger screen area and better touch effect. In order to meet the needs of consumers, the screen from LCD to LED, and then to the new generation of LED on the market, visible screen factory in how to improve the screen display effect on the hard work.

What is transmittance, haze, and clarity? Total transmittance is the ratio of transmitted light to the incident light. Its equation is Transmittance= Tt/T1. Haze is how blurry or cloudy the appearance of a transparent material is.

The cell phone screen is basically divided into four layers.
    The first layer is the phone cover, which is where we often touch. This layer of transparent material to resist the impact of external forces and direct contact with the role of the finger. We often hear the gorilla Corning glass, sapphire glass, etc., is said to be this layer of material. The second layer is the touch sensor, divided into resistive screen and capacitive screen. Nowadays, smart phones are basically using capacitive screens. The role of this layer is to respond to the finger touch. The third layer is the LCD screen, from the traditional flat LCD to the current flexible screen, the most core display technology are focused on this level, the most popular LCD screen technology on the market is the flexible oled screen. The last layer is the backlight layer, responsible for light-emitting so that the image of the liquid crystal layer can be presented, liquid crystal for non-light-emitting display devices, need to use the backlight plate to achieve the function of display.
    Haze and transmittance is the screen material two very important optical performance indicators, in the practical application of poor performance screen may reduce the visual perception of consumers, such as pictures look blurry. Cell phone screen materials layer by layer to limit the display effect, so the display effect of excellent screen for each layer of material haze and transmittance requirements are extremely demanding

    Haze and transmittance are two very important optical performance indicators of screen materials, in practice poor performance screen may reduce the visual perception of consumers, such as pictures look blurry.

    GBPI CO., LTD independently developed and produced Light Transmittance and Haze Tester is suitable for testing the light transmittance and haze of a variety of transparent and translucent parallel plane samples (plastic sheet, sheet material, etc.), and the instrument meets the standards of ASTMD1003-2007, JISK7105-81, etc. The instrument has user-friendly operating system, convenient testing and high efficiency, and can be used for the testing of light transmission/haze of cell phone screens and other materials.

    In the field of screens, manufacturers in recent years chase, has begun to rise, although the country has not yet developed relevant standards for regulating screen light transmission, haze and other specific parameters, it is foreseeable that in the future the standard of domestic screens will become higher and higher, domestic manufacturers will naturally adopt in large quantities, with the rising sales of domestic cell phones, domestic screens will soon usher in the best era of development.

    GBPI CO., LTD is a supplier of flexible packaging testing equipment , mask testing equipment , and testing solutions. It has more than 20 years of experience in the field of testing equipment. The company has a dedicated R&D and after-sales team, which can accept customer testing and on-site teaching machine services.
