Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] A display screen row scanning driving method of the present invention specifically comprises: encoding the scanning output signal, then performing a digital decoding on the encoded signal, and then performing an analog decoding on the digitally decoded digital signal, The scanning signal output by analog decoding is directly sent to the row scanning line of the display screen.

[0029] Here, the encoding is specifically performed by a programmable chip; the digital decoding is specifically performed by a programmable chip; the analog decoding is specifically performed by an ADG506A.

[0030] The display screen is specifically an OLED screen. Those skilled in the art can see that the row scanning driving method for the display screen here can also be used for driving other display screens.

[0031] The display screen line scanning drivi...

Abstract

The invention discloses a line scanning driving method and a platform for a display screen. The driving method particularly comprises the following steps: scanning output signals are subjected to coding, and then the coded signals are subjected to primary digital decoding; the digital signals subjected to digital decoding are subjected to primary simulation decoding; and the scanning signals output through simulation decoding are directly sent to the line scanning lines of the display screen. The driving platform adopted by the invention comprises a coding control unit, a digital decoding unit and a simulation decoding unit. According to the line scanning driving method provided by the invention, through coding, decoding and re-decoding, the driving for the display screen is completed, and the scanning driving for the display screen in optional size and optional driving requirements can be effectively and flexibly realized. According to the driving platform based on the driving method, through the coding, decoding and re-decoding, the pins of the scanning driving signal output by a programmable chip can be greatly reduced, and the flexibility of the scanning driving is maintained, and the development for the high-performance display screen is effectively supported.

Description

technical field [0001] The invention belongs to the technical field of display driving, and in particular relates to a display screen row scanning driving method and platform design. Background technique [0002] OLED (Organic Light-Emitting Diode) display screen is regarded as the most potential new flat display technology in the next generation, and it has many incomparable advantages of LCD. [0003] As one of the core technologies of OLED display, drive technology is the key to the successful development of high-performance OLEDs. However, the design of dedicated drive ICs often lags far behind the development of display screens, and the cost is high, which has become a factor restricting the development of OLED manufacturers. Therefore, developing an OLED drive platform and mastering the design technology of the platform by itself, providing software and hardware support for the research of OLED drive technology, is one of the core capabilities that an open OLED must po...
