Abstract
The utility model relates to an LCD (liquid crystal display) module comprising an LCD display screen and an LED (light-emitting diode) backlight, wherein the LCD display screen adopts a COG (Chip On Glass) bonding technique, a raster graphic driving COG IC (integrated circuit) and a pen section driving COG IC are bonded so as to realized the fact that a raster graph and a pen section are driven at the same time on a bilateral step, the raster graphic driving COG IC and the pen section driving COG IC are respectively connected with an external control chip MCU (micro control unit) by virtue of respective FPC (flexible printed circuit) connectors; and an LCD controller and an LCD driver are all integrated inside the raster graphic driving COG IC and the pen section driving COG IC. The LCD module provided by the utility model has the advantages that the raster graph and the pen section can be displayed on the same LCD display screen at the same time, the LCD module is small in volume and is convenient to mount, and the LCD module is a COG liquid crystal display module which is ultra-low in power consumption and is provided with a heating plate.
Description
Technical field
The utility model relates to a kind of LCD LCD MODULE, concrete relates to a kind of COG LCD MODULE that can realize on a LCD screen that dot pattern and pen section show simultaneously.
Background technology
The LCD screen is as main display device; Be widely used in numerous areas such as national defence, industry, family expenses, communal facility, industrial control instrument display requires than higher: must be that volume is little, the operating temperature range of broad, low-power consumption, the various numerals of demonstration and character.Size LCD in traditional instrument; Can only show on LCD screen a kind of in dot pattern and the pen section to show dot pattern and pen section if desired simultaneously, just need two modules; This has just caused the instrument volume big; Processing technology is complicated, and especially static current of lcd is high, can not satisfy the low-power consumption requirement.
Summary of the invention
The purpose of the utility model provides a kind of COG LCD MODULE, can realize on same LCD screen that dot pattern and pen section show that simultaneously volume is urinated in installation, the COG LCD MODULE of the band heating plate of super low-power consumption.
For realizing above-mentioned purpose, the utility model is realized through following technical scheme:
A kind of COG LCD MODULE; Comprise LCD display, LED-backlit source; Said LCD display adopts the fixed technology of COG nation; Simultaneously nation's fixed point system of battle formations shape drives COG IC and drives a COG IC with the pen section and on the bilateral step, realizes driving simultaneously dot pattern and pen section, dot pattern drive COG IC and pen section driving COG IC respectively the FPC connector through separately be connected with external control chip MCU; Said dot pattern drives COG IC and drives COG IC inner all integrated LCD controller and lcd driver with the pen section.
Be provided with heating plate between said LCD display and the LED-backlit source.
Said FPC connector adopts polyimide to do base material.
Said LCD display adopts the half-reflection and half-transmission display mode.
One-sided luminous five SMT wicks are adopted in described LED-backlit source, and brightness guarantees at 400cd/m
