Abstract
The invention discloses a stroke-segment-type COG (Chip-on-Glass) LCD (Liquid Crystal Display) module, which comprises an LCD screen and an FPG (Flexible Printed Circuit) board. The LCD screen adopts a COG IC (Integrated Circuit) chip for binding and statically driving seventy-six stroke segments. The COG IC chip is electrically connected with an external control chip through an FPC board. A backlight is arranged below the LCD screen. The COG IC chip is ML1001-2U. Eighty data ports and eighty display buffer memories which are respectively and electrically connected with the stroke segments are built in the COG IC chip. Since the LCD screen adopts the COG IC chip for binding and statically driving the seventy-six stroke segments and the COG IC chip is ML1001-2U, compared with the traditional driving chip, the ML1001-2U can provide stronger contrast, wider view angles and a wider range of working voltage and working temperature; besides, in the aspect of the number of the stroke segments, the eighty data ports can fully meet the requirements of the seventy-six stroke segments and the requirement on the range of view angles, and the display module is further enabled to have better contrast, wider view angles and a better display effect.
Description
Technical field
The present invention relates to field of liquid crystal display, relate in particular to a kind of segmentation COG LCD MODULE.
Background technology
Volume is frivolous, little, the advantage such as radiation is little takes up room because it has for LCD MODULE, occupied gradually the main flow that shows product, the requirement of display module is more and more higher at present: little, the wider operating temperature range of volume, contrast, wider angular field of view etc. preferably as much as possible.Existing LCD MODULE is on the market to adopt LCD product that Multiplex method drives, and this type of drive exists the defects such as contrast is low, angle of visibility scope is little, operating temperature range is little, therefore cannot meet the demand in market.
Summary of the invention
For the weak point existing in above-mentioned technology, the invention provides the segmentation COG LCD MODULE that a kind of contrast is strong, angle of visibility scope is wide, operating temperature range is wide and display effect is good.
For achieving the above object, the invention provides a kind of segmentation COG LCD MODULE, comprise LCD display and FPC plate; Described LCD display adopts COG IC chip bonding and 76 pen sections of static drive, and described COG IC chip is electrically connected to external control chip by FPC plate, and the below of described LCD display is provided with backlight; Described COG IC chip is ML1001-2U, and described COG IC built-in chip type has 80 FPDP and 80 the aobvious buffers of looking that are electrically connected to pen section respectively.
Wherein, described COG IC chip is also built-in with the electromagnetic shaker being electrically connected to FPC plate respectively and flashes controller.
Wherein, described display module also comprises metal pin, and described COG IC chip is electrically connected to FPC plate by metal pin.
Wherein, described LCD display comprises a plurality of numeral demonstrations and a plurality of letter demonstration, and often the spacing between adjacent two numeral demonstrations is 2.3mm, and each numeral demonstration is of a size of 3.7mm*7.5mm.
The invention has the beneficial effects as follows: compared with prior art, provided by the invention segmentation COG LCD MODULE, LCD display adopts COG IC chip bonding and 76 pen sections of static drive, simultaneously, COG IC chip is ML1001-2U, compares with conventional ADS driving chip, and ML1001-2U can provide more striking contrast degree, more wide angle of visibility, wider operating voltage and working temperature; In addition, ML1001-2U is more built-in with 80 FPDP and 80 aobvious buffers of looking, on a hop count, 80 FPDP can meet requirement and the angular field of view requirement of 76 pen sections completely, further impel this display module to have better contrast, larger visual angle and better display effect.The present invention has that volume is little, low in energy consumption, view effect is good, contrast is strong, angle of visibility scope is wide and the feature such as operating temperature range is wide.
