Embodiments of the present disclosure provide a color film substrate and a method for preparing the same, and a display device. The color film substrate comprises a substrate; a first black matrix located on the substrate; and a second black matrix partially overlapping with the first black matrix, wherein at an overlapping position of the first black matrix and the second black matrix, the second black matrix overlays the first black matrix in a direction perpendicular to the substrate, and wherein a size of an opening defined by either of the first black matrix and the second black matrix is larger than a size of an opening defined by the first black matrix and the second black matrix together.

A multiuser downlink multiple-input multiple-output (MIMO) system with limited channel information feedback includes an error-free channel vector quantization scheme. Each user has multiple antennas, and the base station includes a matching number of antennas. Each MIMO channel is measured at the terminus end of a corresponding user, and used to obtain the channel state information at the receiver (CSIR). A few data bits of CSIR information are feed back to the base station through the limited feedback channels. The base station collects all these CSIR feedback data bits into a CSI at the transmitter (CSIT). The CSIT is used to determine which users are served, and how to configure a corresponding multi-user precoder. The user data channels will later all be transmitted through such precoder. A codebook of channel quantization vectors is pre-defined and distributed amongst the base station and all the users.
