基于DisplayPort接口的显示设备设计

Design of Display Device Based on DisplayPort Interface

介绍了DP显示设备的设计技术,提出相关的设计技术、模块结构、开发OSD菜单功能的数据类型以及实现软件功能的有关算法。研究和开发了相应的软件和硬件设备,实现了自动调整算法。此外,提出了使用多功能软件开关选择与电路相匹配的配置,通过RS232或者I2C通信通道可修改设置,提高软件的灵活性。所开发产品通过各项测试符合设计规格,表明DislpayPort技术能获得更好的显示效果。

Design technology of display device based on DisplayPort interface was proposed in this paper.The paper proposed the design technology,module structure,data type and arithmetic.The softeware and hardware were studied and developed,and the auto align arithmetic was implemented.Furthermore,the paper proposed the multifunction software,which can config the selection to match with hardware.The config of display device can be modified by RS232 or I2C communicate channel,it improved the flexibility of the software.The test results show that it meets the design specification.It is proved that developer can get better display effect to use DisplayPort technology.
