Embodiment
Under study for action, we adopt a plurality of comparatively cheap Taiwan rhenium moral (Ritdisplay Corporation) full color (65K colour) the small screen (1 inch) products, the OLED video image is carried out dynamic real-time show research.
Since the pixel element be 96 (W) * 3 (R * G * B) * 64 (H), its level is controlled to be 288 lines, vertically is controlled to be 64 lines, considers computer control interface, the external tapping functional schematic of its driver is as shown in Figure 1.Wherein, except that considering analog-and digital-power supply, also should consider the reference voltage adjustment and the electric current adjustment of red, green, blue element, and address and Data Control adopt parallel bus control.
The design frame chart of unitary display driving circuit as shown in Figure 2.Interface in this driver (MCU) both can link to each other with 6800 or 8080 parallel ports, can join with serial ports again, and control is determined by BS0-BS2.Image data random access memory (GDDRAM) is 96 * 64 * 16bits.Sending into corresponding row and column driving after the gray scale of image is decoded through the gray scale yardstick makes the pixel of OLED display correspondence show.Control command for driving circuit is finished by instruction decoder (CommandDecoder), and it not only controls read clock, and the generation of the address of controlling level and vertical drive, therefore, can finish the function of scanning.When the design of this driving circuit, taken into full account versatility, therefore, it can be to line by line scan, and also can be staggered scanning.
Control system adopts DSP or embedded system, and this control system is controlled monolithic or multi-disc driving circuit (band interface and address lookup), makes the luminous as requested demonstration of OLED display, as shown in Figure 3.
A plurality of organic light emitting display dynamic video display drivers, it comprises OLED display, driving circuit, DSP embedded system, timing circuit and control circuit, the DSP embedded system is connected with the MCU interface of driving circuit by data bus and control bus, and connect the Displaying timer generator of driver by timing circuit, the ranks OLED piece that connects driver by control circuit drives, and the output of driving circuit is connected to the OLED display.
Described DSP embedded system is connected with the multi-disc driving circuit with control circuit by data bus, control bus, timing circuit, and each driving circuit is connected with corresponding OLED display respectively.
Above-mentioned driver is equipped with application program again, and it is luminous to control each pixel point, just can show the dot character of various colours.This character that can be applicable to small displays such as mobile phone and instrument shows.The flow process of simple application program is seen Fig. 4.
The little OLED display screen (dot matrix is less, can't know display video image) that character shows is designed to can be than the monitor of large screen display video image.Like this, this driving circuit and control not only can be used for mobile phone and instrument face plate, but also might be used for the demonstration of following TV or monitor.At this moment DSP embedded system not only can produce simple character, and, further expand the function of Flame Image Process.Referring to Fig. 5, it changes into digital picture with the original analog image, and a width of cloth complete image is divided into some width of cloth images, each partitioning portion image converts the display image that can show separately to according to color, gray scale and the saturation degree of gathering, and a plurality of display group synthesize a complete OLED display image.This display is avoided the shortcoming that little demonstration can only character display, display image in real time, and, enlarged display area after a plurality of displays splicings, improved resolution, can comparatively normal display video image.Cost increases limitedly like this, utilize limited fund not only to study driving circuit, and comprise the demonstration control of various video images, thereby finish can have certain displaying degree, general image display driver product more.
For under general dot matrix driving circuit, do not increase hardware cost as far as possible, reach the purpose of the successive dynamic image of display video and several stitching images, the characteristics that have correlativity according to adjacent image, with each width of cloth image pre-service, the information of an images changing unit, and identical image keeps continuous sweep, thereby reduce every width of cloth image data quantity transmitted and speed greatly, guarantee not glimmering of several dynamic stitching images.Referring to Fig. 6, the exchanges data of external cache and driver only is the picture signal and the address signal of changing unit, and the image of same section adopts view data last time.If rest image only needs primary image transmission, and only need repeat to call the view data of driver memory storage subsequently; Iff being localized variation (most applications of determining), only transmit few modified-image information; For large tracts of land sudden change image (as the lightning image etc.), because the sudden change image cannot be sustained, therefore, of short duration high amount of traffic can not cause too big influence.
