背景技术Background technique
电子席卡，也叫电子桌牌，主要用于在会议上显示参会人员的姓名、单位、职务等信息。Electronic table cards, also called electronic table cards, are mainly used to display the names, units, positions and other information of participants in meetings.
传统会议的席卡都是采用纸质或铜质，大多是临时制作，仅仅用来显示人名和提示与会者的身份。一般采用打印、彩印、刻字等方式，外观较为粗糙，无法体现现代化的会议环境。而且每次都是临时制作，用完即弃，遇到参会人员较多时，不仅浪费大量的人力物力，而且制作效率低，污染环境，成本过高，浪费严重。国内绝大多数会议都采用这种传统做法。Traditional meeting cards are made of paper or copper, and most of them are temporary, only used to display names and remind participants of their identities. Generally, printing, color printing, lettering, etc. are used, and the appearance is relatively rough, which cannot reflect the modern meeting environment. Moreover, it is made temporarily every time and is discarded after use. When there are many participants, it not only wastes a lot of manpower and material resources, but also has low production efficiency, pollutes the environment, and the cost is too high and the waste is serious. The vast majority of domestic conferences adopt this traditional approach.
目前市场上的主流电子席卡，以LED显示方式为主，显示效果单一，像素低，对人眼刺激较大，且只能单排显示。少数电子席卡以LCD屏显示，价格偏高，做工粗糙，显示模式少，显示特点不突出，且仅仅支持在会场内使用，无法由与会者进行随身携带。At present, the mainstream electronic mat cards on the market are mainly based on LED display, which has a single display effect, low pixels, great irritation to human eyes, and can only be displayed in a single row. A small number of electronic seat cards are displayed on LCD screens. The price is high, the workmanship is rough, the display modes are few, and the display features are not outstanding. They can only be used in the venue and cannot be carried by participants.
因此，电子桌牌技术领域急需一种多功能便携式电子席卡及其实现方法，能够使整个显示过程快速流畅，图片显示效果清晰，视频播放流畅，足以满足电子席卡的日常使用要求，能够更好地满足使用者的丰富需求，使会议过程更为生动直观；针对不同模式的设置更有利于系统在不同功耗下工作，使系统整体工作功耗降低，极大地延长了电池的续航时间，节约成本，保护环境。Therefore, there is an urgent need for a multifunctional portable electronic table card and its implementation method in the field of electronic table card technology, which can make the entire display process fast and smooth, the picture display effect is clear, and the video playback is smooth, which is enough to meet the daily use requirements of the electronic table card. It satisfies the rich needs of users and makes the conference process more vivid and intuitive; the settings for different modes are more conducive to the system working under different power consumption, which reduces the overall power consumption of the system and greatly prolongs the battery life. Save costs and protect the environment.
