Abstract

A display driver (200) multiplexes gray-scale data captured by a data latch (300) and outputs a data signal to a comb-tooth distributed data line. The data latch (300) includes a gray-scale bus (310) to which the gray-scale data for first to third color components is supplied corresponding to the arrangement order of the data lines. A first data latch, a second data latch, a first shift register, a second shift register, a first clock signal line, and a second clock signal line are N multiplexed. A multiplexer (380) multiplexes N sets of gray-scale data captured by the first and second data latches. The display driver (200) outputs the data signal corresponding to first or second multiplexed data to a data signal supply line.

Description

technical field

[0001] The invention relates to a display driver and a photoelectric device. Background technique

[0002] A display panel (in a broad sense, a photoelectric device or a display device) represented by an LCD (liquid crystal display) panel is mounted on a mobile phone and a portable information device (Personal Digital Assistants: PDA). In particular, compared with other display panels, LCD panels are more compact, lightweight, low power consumption, and low cost, and are used in various electronic devices.

[0003] Considering the clarity of images displayed by the LCD panel, the size of the LCD panel is required to be greater than or equal to a certain fixed size. On the other hand, when it is installed on an electronic device, the installation size of the LCD panel is required to be as small as possible. Such an LCD panel capable of reducing the mounting size refers to a so-called comb wiring LCD panel.

[0004] An effective way to reduce the installatio...
