Description
Technical field
The utility model relates to the electronic function device field, relates in particular to be used for Liquid Crystal Module (LCM).
Background technology
Liquid crystal display (LCD) is a kind of flat-panel monitor of superior performance because its special advantages like advantages such as free from glare, long-life, power saving, low radiation, is widely used in the various electronic products.But liquid crystal itself is not luminous, therefore, needs auxiliary backlight illumination.
LCM (LCD Module) is a LCD MODULE; Be meant that the LCD that liquid-crystalline glasses (LCD) and lcd driver are integrated together shows product; The LCM liquid-crystalline glasses of comparing is a kind of LCD product of more high integration; Small size LCD is shown that LCM can be connected with various microcontrollers eaily.The liquid crystal display driving of color liquid crystal module (LCM) needs a lcd drive chip, and the backlight of LCM also needs a backlight driver chip.Like this, the problem of existence is: need lcd drive chip and backlight driver chip in the colorized lcd display model simultaneously, cause the cost of LCD MODULE higher, and controlling schemes is complicated.
The utility model content
To these above-mentioned deficiencies, the utility model proposes a kind of color liquid crystal module (LCM) that only can realize color LCD screen drive controlling and backlight driver control through a chip unit.
The technical scheme of the utility model is:
The colorized lcd display model of the utility model comprises:
One micro controller unit, this micro controller unit electrically is connected to a liquid crystal and backlight control drive unit through the I/O port;
One liquid crystal and backlight control drive unit, the I/O port of this liquid crystal and backlight control drive unit is connected to above-mentioned micro controller unit, and its COM port and SEG port are connected to a liquid crystal display control element, and its backlight drive port is connected to a LED-backlit source unit;
One liquid crystal display control element, this liquid crystal display control element is connected to above-mentioned liquid crystal and backlight control drive unit;
And a LED-backlit source unit, this LED-backlit source unit is connected to above-mentioned liquid crystal and backlight control drive unit.
Further, described liquid crystal display control element is a TN type liquid crystal display control.
Further, described LED-backlit source unit is the three-primary color LED backlight.
The utility model adopts as above technical scheme, and the program through micro controller unit realizes liquid crystal and the controlling and driving signal of backlight control drive unit output liquid crystal display control element and the controlling and driving signal of LED-backlit source unit.The controlling schemes of the utility model is comparatively simple, and cost is also cheaper, therefore, has more business market and is worth.
