Embodiment 1

[0037] This embodiment provides an LCoS display board, as attached figure 1As shown, the LCoS display board provided by this embodiment includes a signal conversion module and an input interface (not marked in the figure) and an output interface (not marked in the figure) connected to the signal conversion module; wherein, the input interface and The signal source 100 is connected to receive the first signal S1, the output interface is connected to the LCoS chip 200 to output the second signal S2, and the signal conversion module is configured to convert the first signal S1 into the second Signal S2; the second signal S2 includes an LCoS data signal for driving the LCoS chip.

[0038] Preferably, in one of the exemplary implementations, the signal conversion module includes a standard interface IC unit 300 and an LCoS interface dedicated IC unit 400 . The input interface includes the input end of the standard interface IC unit 300 (not shown in the figure), and the output int...

Embodiment 2

[0049] See attached image 3 , is a schematic structural diagram of an LCoS display board provided in this embodiment. The difference from Embodiment 1 is that the signal conversion unit in an LCoS display board library provided by the present invention includes a dedicated IP core A programmable logic device 500, the dedicated IP core is used to convert at least one of the first signal S1 into the second signal S2. Compared with Embodiment 1, the LCoS display board provided in this embodiment integrates the standard interface IC unit 300 and the LCoS interface in Embodiment 1 by implanting a dedicated IP core in the programmable logic device 500. The dedicated IC unit 400 integrates resources, thereby unifying the hardware platform and simplifying the design and layout of the hardware layout. Wherein, the programmable logic device 500 may be a programmable dedicated device of Xilinx. Obviously, this is only a description of a preferred implementation mode, and is not a limit...

Abstract

The invention provides an LCoS display board card and display equipment. The LCoS display board card comprises a signal conversion module, an input interface and an output interface, wherein the inputinterface and the output interface are connected with the signal conversion module, wherein the input interface is connected with a signal source and used for receiving a first signal, the output interface is connected with the LCoS chip and used for outputting a second signal, and the signal conversion module is configured to convert the first signal into the second signal; the second signal includes an LCoS data signal for driving the LCoS chip. According to the LCoS display board card provided by the invention, the problems of complex LCoS signal butt joint and inconvenience for system integration of LCoS application in the prior art are solved, the system integration difficulty of subsequent LCoS application can be reduced, and convenience is provided for popularization and application of LCoS.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display on silicon, in particular to an LCoS display board and a display device. Background technique [0002] Liquid Crystal on Silicon (LCoS) display is a very small matrix liquid crystal display device based on reflection mode. This matrix is ​​processed on a silicon chip using CMOS technology. Belonging to the field of control circuits and driver chips, the LCoS chip is the core of LCoS. It is a dedicated chip made by integrating the display matrix and related driver circuits on a silicon chip using a design and manufacturing method compatible with large-scale integrated circuits. LCoS is a new type of flat panel display technology with development prospects. Compared with other display technologies, it has a series of advantages such as wafer-free mode, wide range of product sources, open architecture, and low-cost potential, making it a future high-end information technology. One of ...
