The utility model discloses an integrated optical fiber isolator for a laser in the field of optical devices, which comprises an integrated optical fiber, the integrated optical fiber comprises an optical fiber body and a plurality of micro-nano structure pairs positioned in the optical fiber body, and the optical fiber body comprises a core layer and a cladding. The included angle between the micro-nano structure pair and the forward transmission direction of the integrated optical fiber is smaller than 90 degrees, so that the micro-nano structure pair is coupled with light which is reversely transmitted in the core layer. According to the utility model, the micro-nano structure is processed on the optical fiber body, and the micro-nano structure is utilized to realize the isolation of the reverse light, thereby not only reducing the damage of the reverse light to the device, but also being higher in integration level and smaller in size of the whole isolation device, and reducing the risk of damage.

The invention relates to the field of video display chips, in particular to a high-reliability DBI interface design suitable for a DSI command mode, which comprises a DBI bus transceiver module, a DCS decoding module and a data flow conversion and transceiver module, according to a DSI command mode interface function, bidirectional communication requirements are considered, forward transmission can be divided into three steps of DBI bus data receiving, DCS command set command analysis and DSI data stream conversion and sending, reverse transmission can be divided into two steps of DSI byte stream receiving and conversion and DBI bus sending, and functions are realized through modularization.
