Simple Active Matrix LCD Bias Supply Operates from Battery Input - 02/03/00 EDN-Design
Ideas: Many active-matrix-LCD applications need multiple voltages for
thin-film-transistor (TFT)bias. Typically, three voltages are necessary: 5V for the
column driver; a positive voltage, such as 10V; and a negative voltage, such -5V, for
the TFT gate drive, or row driver. For handheld electronic devices, a
battery.....(design idea added 11/05) |

Simple VCOM adjustment uses any Logic Supply Voltage - 09/30/04 EDN-Design Ideas:
All TFT (thin-film-transistor)LCD panels require at least one appropriately tuned VCOM
signal to provide a reference point for the panel's backplane. The exact value of VCOM
varies from panel to panel, so the manufacturer must program the voltage at the
factory to match the characteristics of each screen.....(design idea added 6/06) |

Single-ended driver for a Circlotron OTL - Originally, this circuit was driving a
6B4G PP output stage. Transformer-coupled, naturally. I started with cap-coupled
Mullard splitter using three 4P1L direct-heated loktal pentodes. Not bad at all, but
had insufficient gain. Then I tried a plain Loftin-White configuration with a LL1660
interstage (this one is a one-of-a-kind custom 30mA version...(schematic added 05/08) |
