The utility model discloses can only can realize functions such as control, drive, DCDC conversion with a COG IC chip the environmental work below 30 degrees below zero, adopt the TFT technology to extend visual angle color display, the man -machine interdynamic of being convenient for of adoption capacitive touch panel.
Description
Technical field
The utility model relates to a kind of LCD LCD MODULE, particularly relates to a kind of capacitive touch screen laser printer TFT display and control assembly.
Background technology
LCD screen is as principal display device, be widely used in the numerous areas such as national defence, industry, family expenses, communal facility, current display requires more and more higher: the operating temperature range that volume is little, wider as far as possible, low-power consumption, wider angular field of view, show various word.Size liquid crystal display device in traditional 320 × 240, adopt SMT structure, need controller IC, memory IC, driver IC, DC/DC power-switching circuit IC, bias circuit, temperature-compensation circuit, volume is large, processing technology is complicated, especially static current of lcd is high, can not meet low-power consumption requirement and cannot realize the display of wide viewing angle colour, human-computer interaction is complicated.
Summary of the invention
The utility model provides a kind of capacitive touch screen laser printer TFT display and control assembly, can the environmental work of subzero less than 30 degree, only can realize the functions such as control, driving, DC/DC conversion with a COGIC chip, adopt TFT technology to realize the display of wide viewing angle colour, adopt capacitance touch screen to be convenient to human-computer interaction.
In order to achieve the above object, the utility model realizes by the following technical solutions:
A kind of capacitive touch screen laser printer TFT display and control assembly, comprises the middle size TFTLCD display screen of 3.5 inches; The fixed COGIC chip of described LCD display nation, can drive 320 × 240 lattice pixels; COGIC chip internal is integrated with lcd controller, lcd driver and DC/DC power boost circuit, is connected with outside MCU by FPC; One piece of capacitance touch screen is set above LCD display, below LCD display, is provided with LED backlight.
Described FPC adopts polyimide to do base material.
Described LED backlight adopts luminous 6 wicks of sidepiece, and brightness ensures at 300cd/m
2.
Compared with prior art, the beneficial effects of the utility model are:
1) adopt COG nation to determine technology, compact conformation volume is little, super low-power consumption;
2) use LED backlight, not only make module work at night, but also be convenient to install;
3) adopt TFT technology, the display of wide viewing angle colour can be realized;
4) adopt rgb interface, data rate is fast, can realize video display;
5) adopt capacitance touch screen, be convenient to human-computer interaction.
