Description
Technical field
The invention belongs to the display technique field, relate to a kind of organic LED display device that has the electromagnetic type touch function.
Background technology
At present, the electromagnetic type touching technique is owing to the bearing accuracy height, can obtain the writing pencil angle of inclination and the pressure information that are used for the computing machine typing, do not influence advantage such as screen display quality when being used to show the field, extremely market favor is widely used in equipment such as handwritten computer, drawing screen, plotting sheet, handwriting pad, mobile phone, e-book.Electromagnetic type touches by electromagnetic induction antenna plate, electromagnetic induction control panel and time writer and realizes.The densely covered coil of regularity on the electromagnetic induction antenna plate by the control and treatment of electromagnetic induction control panel, switches the emission of electromagnetic field at a high speed and receives induced electricity magnetic pen information.Concrete principle of work is: the electromagnetic induction control panel is by electromagnetic induction antenna plate emission electromagnetic field, in the magnetic field range that produces, the time writer of built-in resonance electronic loop can be put aside faint energy, by this energy, time writer after the electromagnetic induction antenna plate receives signal, is given electromagnetic induction control panel with its conduction to electromagnetic induction screen emission electromagnetic signal, handle this signal by control panel, calculate coordinate, angle of inclination, mode of operation such as speed, the pressure sensitivity etc. of time writer.Working current in the electromagnetic induction antenna plate coil is big more, and its electromagnetic intensity of launching is just big more, and the height that satisfies the required energy of time writer accumulation emission electromagnetic signal is just high more, and the working depth of time writer is just high more; Otherwise the working current of tablet is little, and electromagnetic intensity is low, and the working depth of time writer is just low more.The tradition electromagnetical type touch screen is based on LCD display, because LCD display has module backlight, the electromagnetic induction antenna plate is positioned at after the module backlight, apart from time writer certain distance is arranged, in order to make time writer working properly, the electromagnetic induction antenna plate must possess bigger working current, and this has increased the power consumption of traditional electromagnetical type touch screen undoubtedly.
OLED is the abbreviation of English Organic Light Emitting Display, the meaning is an organic light-emitting diode (OLED) display screen, its display technique is different with traditional LCD display mode, need not backlight, adopt extremely thin coating of organic material and glass substrate, when electric current passed through, these organic materials will be luminous.Compare traditional LCD display, OLED visual angle broadness, maximum can reach 180 degree; The contrast of OLED is higher, and color is more gorgeous, clear; The OLED screen can be done lighter and thinnerly, and its thickness can be less than 1 millimeter.These advantages of OLED make it be highly suitable for electromagnetic type and touch the demonstration field.
Summary of the invention
The technical problem to be solved in the present invention is: realize the electromagnetic type touch function on the OLED screen, so that a kind of electromagnetical type touch screen of frivolous, power saving to be provided.
Technical scheme
The technical solution adopted for the present invention to solve the technical problems is: with Organic Light Emitting Diode is that OLED screen stacks together with the electromagnetic induction antenna plate, organic light-emitting diode (OLED) display screen driving circuit and electromagnetic induction control panel be placed on the electromagnetic induction antenna plate below.The electromagnetic induction antenna plate back side is first insulation course and an electro-magnetic screen layer and second insulation course.First insulation course is insulated electromagnetic induction antenna plate and electro-magnetic screen layer, and second insulation course is with electro-magnetic screen layer and OLED display driver circuit and the insulation of electromagnetic induction control panel.First insulation course is functional definition, only shows between electromagnetic induction antenna plate and the electro-magnetic screen layer and insulate, and both can be an independent community, as insulating trip etc., also can be insulation course own on the electromagnetic induction antenna plate.The length and width of electromagnetic induction antenna plate is more than or equal to the length and width of OLED screen.The length and width of insulation course, electro-magnetic screen layer is more than or equal to the length and width of electromagnetic induction antenna plate.
The invention has the beneficial effects as follows:
Realized the electromagnetic type touch function of OLED screen, electromagnetical type touch screen frivolous, power saving is provided.
