Title:
DIGITAL-TO-ANALOG CONVERTER AND DISPLAY PANEL COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2017/201826
Kind Code:
A1
Abstract:
A digital-to-analog converter, comprising N rows of transistors. The number of transistors in each row is halved compared with a previous row. Each transistor comprises a conducting end, an input end, and an output end. Input ends of the first row of transistors are used for being connected with a plurality of analog signals. In any two adjacent rows of transistors, input ends of first transistors (101) in the next row and input ends of second transistors (102) in the next row are respectively connected with output ends of first transistors (101) in the previous row; output ends of second transistors (102) in the previous row are respectively connected with output ends of first transistors (101) in the previous row; and output ends of the second transistors (102) in the next row are respectively connected with output ends of the first transistors (101) in the next row. Conducting ends of each row of transistors are mutually communicated. Output ends of two transistors of the last row of transistors are mutually connected. The digital-to-analog converter is capable of implementing digital-to-analog conversion by using fewer transistors. The space occupied by the digital-to-analog converter is reduced. Meanwhile, the costs of the digital-to-analog converter are greatly reduced.
