Abstract
The utility model aims to overcome the shortcoming that the conventional passive-matrix organic light emitting diode (PMOLED) is difficult to be manufactured in large size, and provides a split-screen-driven large-size PMOLED. According to the technical scheme, the split-screen driven large-size passive-matrix organic light emitting diode (PMOLED) comprises a system board with a driving circuit and a driving integrated circuit (IC), a PMOLED display screen and a chip on film for connecting the PMOLED display screen and the system board, the PMOLED display screen is equally divided into at least two groups of small-size PMOLED display regions which are driven independently; and each PMOLED display region is connected with a group of matured driving circuit and matured driving IC in the system board through the chip on film and is controlled by the matured driving circuit and the matured driving IC. The split-screen-driven large-size PMOLED has the beneficial effect that the display size of the PMOLED can be effectively increased, the conventional matured PMOLED display technology can be used, and the cost is not increased.
Description
Technical field
The utility model relates to OLED display technique field, relates in particular to PMOLED display technique field.
Background technology
The OLED display technique is different with traditional LCD display mode, need not backlight, adopts extremely thin coating of organic material and glass substrate, and when electric current passed through, these organic materials will be luminous.And the OLED display screen can do lighter and thinnerly, also can significantly save electric energy.The type of drive of OLED is divided into active driving (active driving) and passive type drives (passive drive), and therefore according to type of drive, OLED also is divided into active driving OLED (AMOLED) and passive drive OLED (PMOLED).
PMOLED has cathode layer, organic layer and anode layer.Anode layer is vertical each other with cathode layer.The point of crossing of negative electrode and anode forms pixel, just luminous position.External circuit applies electric current to cathode layer of choosing and anode layer, thereby determines that which pixel is luminous, and which is not luminous.In addition, the brightness of each pixel is directly proportional with the size that applies electric current.PMOLED is easy to make, but its power consumption is greater than the OLED of other types, and this mainly is because it needs the cause of external circuit.Most effective when PMOLED is used for videotex and icon, be suitable for making the small screen (diagonal line 2-3 inch), for example people on mobile phone, palmtop computer and MP3 player, often can see the sort of.Even if there is an external circuit, the power consumption of passive-matrix OLED still is less than the LCD of the current employing of these equipment.
Because PMOLED exists electrode impedance and capacitive loss, peak brightness height, line number to increase the peak point current cause of increased; So PMOLED is relatively more difficult toward the large scale development; Want to be large-sized OLED; Will research and develop AMOLED, but at present the AMOLED technology that is that all right is ripe, to the requirement of technology, equipment, personnel and factory than higher; So implement the comparison difficulty, thereby the PMOLED that therefore tries every possible means to make in the technical improvement of existing P MOLED giant-screen also is a technique direction being big OLED.
The utility model content
The purpose of the utility model is for the size that overcomes existing P MOLED is difficult to do big deficiency, has proposed the large scale PMOLED that a kind of split screen drives.
The technical scheme of the utility model is: the large scale PMOLED that a kind of split screen drives; Comprise system board, PMOLED display screen that driving circuit and drive IC are installed and the brilliant film that covers that system board is connected with the PMOLED display screen; Said PMOLED display screen is divided into the PMOLED viewing area of at least two group reduced sizes and carries out individual drive, and the PMOLED viewing area of said every part is formed ripe driving circuit and is connected with drive IC and controlled by it through covering in brilliant film and the system board one.
The beneficial effect of the utility model is: because the driving circuit of small-sized PMOLED and drive IC are quite ripe; Therefore a bigger PMOLED being divided into the less PMOLED viewing area of many groups drives separately; Can either effectively increase the display size of PMOLED; The PMOLED display technique of existing maturation can be utilized again, cost can be do not increased.
Description of drawings
The structural principle synoptic diagram of Fig. 1 the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
As shown in Figure 1; The large scale PMOLED that a kind of split screen drives; Comprise system board, the PMOLED display screen that driving circuit and drive IC are installed and system board is connected with the PMOLED display screen cover brilliant film (COF; Chip On Film); Said PMOLED display screen is divided into the PMOLED viewing area of at least two group reduced sizes and carries out individual drive, and the PMOLED viewing area of said every part is formed ripe driving circuit and is connected with drive IC and controlled by it through covering in brilliant film and the system board one.
In the present embodiment, the PMOLED display screen is divided into four groups of PMOLED viewing areas of quarter, does not organize the PMOLED viewing area all through one a group of driving circuit and a drive IC of covering in brilliant film band and the system board.Though only with the PMOLED display screen quartern, those of ordinary skill in the art should look like and arrive here, also can be with PMOLED display screen 2 five equilibriums, 3 five equilibriums until the N five equilibrium, N is a natural number.
Those of ordinary skill in the art will appreciate that embodiment described here is in order to help the principle of reader understanding's the utility model, should to be understood that the protection domain of the utility model is not limited to such special statement and embodiment.Those of ordinary skill in the art can make various other various concrete distortion and combinations that do not break away from the utility model essence according to disclosed these teachings of the utility model, and these distortion and combination are still in the protection domain of the utility model.
