TH17566EX - Data drive circuit for use with an LCD display unit. - Google Patents

Abstract

A data drive circuit (25) and a system drive scheme that can be integrated directly on the base of the display unit (14) to reduce the cost of cyclic integrated circuits and hybrid assemblies. Required by the crystal display unit. An uncensored matrix liquid for bonding it. The multiplexer (102) circuit is accumulated on the display unit (14) for removing one group of multiplexes of Y column, the multiplexed image signal column as X group A group of Y-dot capacitors (94,96, -100) that are also accumulated on the base (14) in the Z row. In addition, the drive circuit (12) provides a voltage signal. To pre-charge the dot capacitor (94,96, -100) at the first voltage in the first period to That the linked data signal is multiplexed during the second period, causing the dot-matrix capacitor (94,96-100) to hold up to a predetermined second voltage to have a display unit. While Rows of image dots are swept sequentially.

Claims (1)

1. A circuit for providing visual information to a display unit which contains a matrix row of point cells in a row and Column, and where the display unit has at least one (14) and second base layers, which one is the glass at Separated by layers of optical-electrical material, the circuit is assembled with Y-column lines (13) accumulated on one base layer (14) X group, group of Y component d multiplexer components (108,110,112,114) accumulated on one such base layer where each component removed. The multiplex is attached to one of the columns.
