Description

Display device and touch control display apparatus

Technical field

The present invention relates to a kind of display device and touch control display apparatus.

Background technology

Along with flat display apparatus (Flat Panel Display; FPD) development of technology; Build is frivolous because of having for liquid crystal indicator, low power consumption and advantageous characteristic such as radiationless; Conventional cathode ray tube (Cathode Ray Tube, CRT) display device, and be applied to various electronic product have been replaced gradually.

Generally speaking, (Liquid Crystal Display Apparatus LCDApparatus) comprises a display panels and a backlight module to liquid crystal indicator.Wherein, display panels mainly has two substrates and and is located in the liquid crystal layer between two substrates.And backlight module sends uniform light to pass display panels, and light can produce colour picture via the modulation of display panels.

Figure 1A is the diagrammatic cross-section of a kind of convention liquid crystal indicator 1a, and liquid crystal indicator 1 comprises a display panels 11, a backlight module 12, a glue frame 13 and a framework 14.Display panels 11 is established with backlight module 12 relatively, and the part of glue frame 13 is extended and is arranged between display panels 11 and the backlight module 12, in order to support display panels 11 and define display panels 11 and backlight module 12 between distance.Display panels 11, backlight module 12 and glue frame 13 are arranged in the framework 14.

Wherein, display panels 11 comprises a thin film transistor base plate (TFT substrate) 111 and one colored optical filtering substrates (CF substrate) 112, and both relatively establish and press from both sides and establish a liquid crystal layer.Backlight module 12 can comprise a luminescence unit 121, a LGP 122, a reflecting element 123 and one group of blooming 124.Be all the convention common technology owing to above-mentioned, so repeat no more.

In the design of liquid crystal indicator 1a; Also can comprise a front housing 16a and a back cabinet 16b and become the appearance component of device, but this mode can make and produce finedraw between front housing 16a and the framework 14, be prone to the accumulation dust or block foreign matter even influence display effect; In addition; The offset that forms between front housing 16a and the display panels 11 can't be accomplished whole planeization, and is visually also not attractive in appearance.

Poor design is shown in Figure 1B and general known techniques is doing not have section, and liquid crystal indicator 1b covers on entire liquid crystal display device 1b with a cover glass (cover glass) 15, and cooperates with front housing 16a and back cabinet 16b.But still can there be a finedraw in (near the side of liquid crystal indicator 1b) between back cabinet 16b and the cover glass 15.

Therefore, the display device and the touch control display apparatus that how a kind of whole planeization are provided and avoid foreign object to get into have become one of important topic.

Summary of the invention

Because above-mentioned problem, the object of the invention also can avoid foreign object to get into for a kind of complanation is provided, and then promotes the display device and the touch control display apparatus of product competitiveness and demonstration usefulness.

For reaching above-mentioned purpose, comprise a display module and according to a kind of display device of the present invention and coat material.Display module has a display surface.A transmittance section that coats material covers this display surface.The coating material more covers a side of display module, and the coating material is essentially seamless in the display surface side.

For reaching above-mentioned purpose, comprise a contact panel, a display module and a coating material according to a kind of touch control display apparatus of the present invention.Contact panel has a touch-control surface.Display module and contact panel are oppositely arranged.A transmittance section that coats material covers the touch-control surface of contact panel.The coating material more covers a side of display module, and the coating material is essentially seamless in the touch-control surface side.

Hold the above, the present invention is through the transmittance section covering display module of coating material or the display surface of contact panel, and the coating material is seamless in fact, makes foreign object can't get into display device inside on the one hand, and then promotes demonstration usefulness; On the other hand; Through coating material as housing and protect display module or contact panel; Make the present invention can become one sturdy and durable and can be independently or the human-computer interface device that uses of combination be prone to collocation with various systems, and then reach complanation, and promote product competitiveness.
