Abstract
The invention provides a manufacturing method for a curved surface display. The curved surface display comprises color filter glass, thin film transistor glass, first curved surface glass and second curved surface glass. The manufacturing method comprises the following steps: pasting the first curved surface glass to the thin film transistor glass to form a first assembly; pasting the second curved surface glass to the color filter glass to form a second assembly; pairing and vacuumizing the first assembly and the second assembly; pouring liquid crystal layers between the first assembly and the second assembly to form the curved surface display. Compared with the prior art, for the method, the thin film transistor glass and the color filter glass are independently bent into the appearance curvatures of the curved surface glass to respectively form the first assembly and the second assembly. After the thin film transistor glass and the color filter glass are paired, the curvatures of the thin film transistor glass and the color filter glass are pulled by the corresponding curved surface glass, so that the gaps between the liquid crystal layers can be effectively maintained, and therefore, the color deviation phenomenon of the curved surface display is improved.
Description
Technical field
The present invention relates to a kind of process technique of display device, relate in particular to a kind of manufacture method of curved surface display.
Background technology
Flat display apparatus (Flat Panel Display, FPD) because having, high image quality, space utilization efficiency are good, low consumpting power, build is frivolous and the advantageous characteristic such as radiationless, gradually replaced conventional cathode ray tube (Cathode Ray Tube, CRT) thus display device becomes the main flow in market.Flat display apparatus is of a great variety, for example liquid crystal indicator, organic LED display device, display device of electronic paper and light emitting display device, and wherein liquid crystal indicator is the flat display apparatus that current technology is the most ripe.Particularly, liquid crystal indicator mainly comprises display panels and backlight module.Wherein display panels comprises colored optical filtering substrates (color filter substrate), thin film transistor base plate (thin film transistor substrate) and is located in the liquid crystal layer between these two substrates.Backlight module has a backlight (as LED lamp bar), in order to provide display panels required light source, makes device reach display effect.
On the other hand, it is that main artistry develops that various consumption electronic products be take design, novel and fashion by functional trend, and consumer is not only functional emphatically, and design and product form more affect the principal element of consumer behaviour.In the prior art, liquid crystal indicator is used the ground as colored optical filtering substrates and thin film transistor base plate without the glass substrate of thinning mostly, and the weight of liquid crystal indicator cannot effectively be reduced.In order to alleviate the weight of glass substrate, make liquid crystal indicator lighter and thin, existing a kind of improvement project is to be to propose a kind of thinning glass substrate, yet, glass substrate belongs to hard substrate, even if glass substrate can alleviate overall weight after thinning, but still cannot make device there is flexural property.For this reason, another kind of existing solution is to be to propose curved surface liquid crystal indicator, and its manufacture focuses on display panels crooked.And its bending method be generally directly to the display panels application of force by its bending.But the method has many defects and unfavorable factor, for example, the colored optical filtering substrates of display panels and thin film transistor base plate all have glass support plate (glass carrier), when directly to the glass support plate application of force, can cause display panels stress to concentrate and make glass support plate break and damage.
In addition, liquid crystal layer gap (cell gap) need be controlled in the disparity range of plus or minus 0.2um, once the difference in liquid crystal layer gap surpasses 0.2um, will cause gamma curve to depart from, and makes device when display frame, occur color offset phenomenon.In the prior art, the liquid crystal layer difference gap of liquid crystal panel before crooked and after bending tends to be greater than 0.2um.For example, when the thin film transistor base plate of panel is upward time, record panel right side and be respectively 3.47um and 3.77um in the liquid crystal layer gap before and after crooked, the difference of same position is up to 0.3um (exceeding 0.2um).And for example, when the colored optical filtering substrates of panel is upward time, record panel left side, centre and the right side liquid crystal layer gap before bending is respectively 3.41um, 3.53um and 3.57um, and liquid crystal layer gap after bending is respectively the difference of 3.86um, 5.08um and 3.77um same position and also reaches respectively 0.45um, 1.55um and 0.2um, reached or exceeded the above-mentioned liquid crystal layer gap difference value controlled of needing.When input is during same luma data, at the diverse location of panel, will present color displacement, affect the display quality of image of device.
In view of this, how designing a kind of manufacturing process of new curved surface liquid crystal indicator or existing making technology is improved, to eliminate above-mentioned defect of the prior art and deficiency, is a person skilled problem urgently to be resolved hurrily in the industry.
