Technology and brand is the basis for development and growth Bobang Cheng Technology Co., Ltd., the years the company has been committed to R & D and brand building, technology-driven business development, brand promotion of products under the guidance of this additional development of ideas, the company launched the BBC brand, its product line includes LCD display wall, Samsung, LG, Sharp LCD screen, ultra-slim bezel LCD splicing screen, LCD monitors, LCD advertising machine, touch one machine, large ultra-wideband RGB matrix, VGA Matrix, AV matrix, multi-screen image processor, Quad and a variety of signal transmission equipment, 360BBC products through rigorous testing to ensure superior stability, the plant will continue to ISO9000 quality system as a guide for the user to create a trusted high value-added products is Bobang Cheng BBC-SD420PD main push plasma splicing products, bilateral patchwork only 1.8MM, brightness up to 1700cd / m, contrast ratio 1,000,000: 1, high color reproduction, improved color consistency, Effective inhibition among the three primary colors of discrete images and color like drift, ensure highly consistent color. No "sun" effect, uniform brightness of the display unit, the entire screen brightness uniformity can reach more than 98%. Advanced screen processing technology, with anti-reflective, high brightness, wide viewing angle, small splicing gap, good uniformity, long-term use is completely without distortion. Its unique integrated built-in image processing systems, can be a variety of standard video signals, analog / digital signals and the computer network-compatible signals, thereby to meet the increasing demand for digital display. 1. narrower patchwork: 0.9mm, approximately DLP rear projection splicing gap, high definition video circuit diagram and give a more perfect display. 2. The higher color reproduction: 97% color gamut, rich colors, gorgeous screen. 3. higher resolution: 1024x768, the original 42-inch PDP splicing units: 853x48. The higher contrast: one million to 1, completely without loss of light and dark detail reproduction. 5. Wide Viewing Angle: 179 ° / 179 ° (horizontal / vertical), to meet a variety of display applications. 6. Long life: 100,000 hours, 100,000 hours of uninterrupted support of continuous work.
