Abstract
The invention relates to an LCD (liquid crystal display) module which comprises an LCD screen and an LED (light emitting diode) backlight source. The LCD screen adopts a COG binding technology; a dot matrix graph driving COG IC (integrated circuit) and a stroke segment driving COG IC are simultaneously bound on a double-sided step to simultaneously drive a dot matrix graph and a stroke segment; the dot matrix graph driving COG IC and the stroke segment driving COG IC are connected with an external control chip MCU (micro control unit) through respective FPC (flexible printed circuit) connectors; and the dot matrix graph driving COG IC and the stroke segment driving COG IC are respectively integrated with an LCD controller and an LCD driver. According to the invention, the dot matrix graph and the pen segment can be simultaneously displayed on the same LCD screen; and the COG module has the advantages of small volume, convenience in installation and ultralow power consumption, and is provided with a heating plate.
Description
Technical field
The present invention relates to a kind of LCD LCD MODULE, concrete relate 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 this invention is to provide 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 present invention realizes 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

Embodiment
With reference to accompanying drawing and combine embodiment, specify embodiment of the present invention below.
Referring to shown in Figure 1, a kind of COG LCD MODULE comprises that LCD display 1, FPC connector 2, pen section drive COG IC3, dot pattern drives COG IC4, FPC connector 5, heating plate 6, LED-backlit source 7.Said LCD display adopts the fixed technology of COG nation; Nation's fixed point system of battle formations shape drives COG IC 4 and drives COG IC 3 on the bilateral step with the pen section simultaneously; Dot pattern drives COG IC 4 and is connected with external control chip MCU through FPC connector 5; Pen section drives a COG IC3 through FPC connector, and 2 are connected with external control chip MCU.Said dot pattern drives COG IC and drives COGIC inner all integrated LCD controller and lcd driver with the pen section.Be provided with heating plate 6 between said LCD display 1 and the LED-backlit source 7, LCD display is applicable to work under the low temperature.Said heating plate 6 adopts the PET film of band ITO (Indium Tin Oxides, indium tin oxide), and electrode connects with metal pin draws, and is assemblied between LCD display 1 and the LED-backlit source 7.
Said FPC connector 2 adopts polyimide to do base material with FPC connector 5.Said LCD display 1 adopts the half-reflection and half-transmission display mode.One-sided luminous five SMT (Surface Mounted Technology, surface installation technique) wick is adopted in said LED-backlit source 7, and brightness guarantees at 400cd/m
2
External control chip MCU passes through I
2C interface drives COG IC to dot pattern and imports data respectively with pen section driving COG IC, is then written to the corresponding position of LCD display through calculating by programmed control, so understands on a LCD screen, to show dot pattern, pen section content simultaneously.
