For instance, a plurality of units or components may be combined or integrated to another system, or some features may be omitted or may be not executed. In addition, displayed or discussed mutual coupling or direct coupling or communication connection may be performed via some interfaces, and indirect coupling or communication connection between units or modules may be in an electrical form or other forms. 
     The units illustrated as separate parts may be or may not be physically separated. Parts for unit display may be or may not be physical units. That is, the parts may be located at a place or may be distributed on a plurality of units. The aims of the solutions of the embodiments may be achieved by selecting some or all units according to actual requirements. 
     In addition, all function units in all embodiments of the disclosure may be integrated in a processing unit, or each unit may exist separately and physically, or two or more units may be integrated in a unit. The integrated unit may be implemented in a hardware form or may be implemented in a software function unit form. 
     If the integrated unit is implemented in the software function unit form and is sold or used as an independent product, the product may be stored in a computer readable storage medium. Based on this understanding, the technical solutions of the disclosure may be substantially embodied in a software product form or parts contributing to the related art or all or some of the technical solutions may be embodied in the software product form, and a computer software product is stored in a storage medium, including a plurality of instructions enabling a computer device, which may be a personal computer, a server or a network device, to execute all or some of the steps of the method according to each embodiment of the disclosure. The storage medium includes: various media capable of storing program codes, such as a U disk, a Read-Only Memory (ROM), a Random Access Memory (RAM), a mobile hard disk, a magnetic disk or an optical disc. 
     The control system and method for data transmission, the chip array and the display according to the disclosure are described in an exemplar mode with reference to the drawings as above. However, those skilled in the art shall understand that various improvements may be made on the control system and method for data transmission, the chip array and the display provided by the disclosure without departing from the contents of the disclosure. 
     The above is only preferred implementations of the disclosure. It shall be pointed out that those skilled in the art may also make some improvements and modifications without departing from the principle of the disclosure. These improvements and modifications shall fall within the protective scope of the disclosure.
