Xi'an led display | led manufacturers Xi'an | Xi'an led the company | Shaanxi led display | Xi'an LED electronic display wholesale supply system features and Advanced 1, multimedia control multimedia control technology is through A / D capture technology, the analog signal ( Video, VGA, etc.) into a digital signal, after computer processing, and then sent to the display. Display control is equipped with a multimedia video card on your computer can be a variety of video sources (CATV, VCD, DVD, video camera, etc.) into the big screen. Through audio and video switching matrix, can be a variety of audio and video unified management. Multimedia control technology, screen brightness, contrast, color saturation adjustments to ensure playback screen. 2, the motion compensation picture Screen when displaying a video image, sometimes the object displayed in a rapid movement, and image mode burnt prone to smearing, is not conducive to viewing and imaging. To this end, the company designed the motion compensation circuit to solve this problem, make the images clearer and more stable. 3, the image noise reduction technology, the display image more clean and smooth. 4, an image edge enhancement technology to display images clearer, more realistic, stronger sense of hierarchy. 5, contrast enhancement technology, the image display more layered. 6, using 8192 video non-linear calibration technology for computer processing, data display and output is linear, and the human eye perception of light will change with changes in ambient light changes greatly, so the human eye to distinguish the brightness is nonlinear a. In order to display the video image of the human eye to adapt to the needs of non-linear, to achieve realistic effects, must be non-linear correction. Based on physiological characteristics of the human eye vision requirement linear display data to the non-linear conversion process must have sufficient space for expression value differences. Specifically, in the low grayscale range, the level difference between the adjacent display is a multiple of the basis; and in the high grayscale range, the level difference between adjacent display is in the low grayscale range phase o Displays the number of times the difference between the levels is based. Example: 256 grayscale data, a difference between the two and more than double the brightness: The brightness difference between 255 and 254, and two compared to the difference in brightness between a difference of more than 50 times. In the data processing requirements such conditions, a relatively small space conversion value, such as 512, 1024 and so difficult to achieve realistic display, and I am using the 8192 video non-linear calibration technology, true reproduction of the source image picture color effects. 7, white balance processing is an important measure of balance display colors. An important method to ensure the balance is the choice of stable performance, high luminous efficiency of light emitting devices. Our full-color selection NIchia company Nichia pure green, blue LED light tube. Secondly, Shaanxi Hi-Tech Optoelectronic Technology Co., Ltd. has a unique dynamic white balance control theory, dynamic brightness, color temperature fluctuation ± 50K. Third, through intelligent distribution system, enabling switching cooling device to control screen temperature rise to ensure LED light tube light emission wavelength is not shifted, it does not affect the display of white balance. 8, constant current source driver current source drive circuit directly to a single LED light tube is driven, so that the input current of each LED tube size constant, thus ensuring the consistency of each light-emitting tube lighting effects, to make the display screen brightness uniform, smooth over. 9, high frequency transducer frame technology Shaanxi Hi-Tech Optoelectronic Technology Co. screen, the screen refresh rate is greater than 240 frames / sec, to fully meet the requirements of video image is displayed, ensure strong dynamic motion picture, and the whole picture jitter and flash frequency phenomenon, with excellent dynamic display. 10, "three" technique based on the use of environment-specific display of the project, in order to prevent the board after a long period of use are subject to normal playback corrosion, impact matrix screen, I am in the body of the screen and all boards are made of a unique structure The "three" technique (moisture, mildew, salt spray), ensure that the circuit board 16 years without corrosion. After "three" process, highly insulated circuit board subjected to immersion in salt water from seven days without any corrosion test. At the same time, the board, after treatment, with a strong anti-electromagnetic interference. 11, the sun outdoor display contrast technique in order to achieve a clear picture visual effects in strong sunlight, the module surface of unique design and injection molding, can not direct the arc tube after the sun refracted through twice, and black modules absorb the sun non-reflective, so that the display in direct sunlight conditions remain clear picture. 12, the optical fiber transmission technology using optical fiber transmission, can completely overcome the balanced transmission cable presence of anti-interference ability, channel frequency narrow, poor adaptation to temperature changes, so that the signal long-distance transmission breeze.
