Embodiment Construction
[0020] The specific implementation manner of the present invention will be described in further detail below by describing the best embodiment with reference to the accompanying drawings.
[0021] Such as figure 1 , 2 As shown, a silicon-based OLED micro-display control system, the micro-display drive control system includes a plurality of functional chips, the functional chips are divided into two groups, the first group is the drive control chip, the second group is the display chip, the drive control chip Assembled on the display chip by bonding or bonding. Each group of chips is a chip or a collection of multiple chips.
[0022] In this application, the drive control chip and the display chip are electrically connected, and an appropriate voltage signal is transmitted to the pixel array circuit through digital voltage signal transmission for driving the OLED array device. The drive control chip obtains the drive control signal according to the control signal of the exte...

The invention discloses a silicon-based OLED (Organic Light Emitting Diode) micro-display control system, which comprises a plurality of functional chips, the functional chips are divided into two groups, the first group is a driving control chip, the second group is a display chip, and the driving control chip is assembled on the display chip in a bonding or bond i ng mode. The method has the advantages that the problem of layout of an integrated circuit module can be solved by fragmenting a traditional single chip in a COC mode, the advantages of I C-I and I C-II are respectively used after the Chip On Chip is combined, and the complexity in the chip and the chip cost are reduced. COC driving and control are combined, so that interconnection and cooperative work of a driving control chip and a display chip can be realized, and the control problem of COC practical application is solved.
Description
technical field [0001] The invention relates to the technical field of silicon-based OLED display, in particular to a silicon-based OLED microdisplay control system and method based on COC (chip On chip). Background technique [0002] Silicon-based OLED microdisplay technology is a combination of OLED optoelectronic technology and silicon-based integrated circuit microelectronic technology. It is mainly used in the field of near-eye microdisplay. OLED microdisplay technology uses mature CMOS integrated circuit technology. Making silicon OLED devices, the performance requirements of OLED-based IC chips are gradually increasing, and the functions are continuously added according to the application scenarios, which makes the IC design increasingly complex, increases the difficulty of the IC process and brings the risk of poor process, and continuously promotes IC re-revision ,increase cost. Therefore, it is necessary to adopt new design schemes and improve process capabilities...
