SM4109

Description

The SM4109 consists of four internal-switch regulators (main boost converter, 3.3VDD buck converter, HAVDD buck converter and 1.2VDD buck converter), two external switch regulators (VON boost converter and VOFF buck-boost converter), a negative linear regulator and a high voltage level shifting scan driver.

The main boost converter and the synchronous buck converter provide the regulated supply voltage for the panel source driver ICs. The 3.3VDD buck converter provides the supply voltage for I/O interface of the T-CON and other logic circuits.

Display Face Configuration

The LCD driver is 80 bits LSI, consisting of shift register, latch circuits, and LCD driver circuits. Display data which is externally divided into data for each row (320 dots) is sequentially transferred in the form of 4-bit parallel data through shift registers by Clock Signal CP2 from the left top of the display face.

When data of one row (320 dots) has been input, they are latched in the form of parallel data for 320 lines of signal electrodes by Latch Signal CP1. Then the corresponding drive signal is transmitted to the 320 lines of column electrodes of the LCD panel by the LCD drive circuits.
