The foregoing is the core idea of the present invention, and the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without making any inventive effort are intended to fall within the scope of the present invention.
Fig. 3 is a schematic plan view of a touch display module provided by the embodiment of the invention, fig. 4 is a cross-sectional view of the touch display module in fig. 3 along a line b-b', as shown in fig. 4, the touch display module 1 includes a display module 11, the display module 11 may be a liquid crystal display module, the liquid crystal display module specifically includes a backlight module and a liquid crystal display panel disposed on a light emitting side of the backlight module, the backlight module may provide a backlight source for the liquid crystal display panel, so that the liquid crystal display panel controls opening of each pixel unit through a driving circuit to enable the backlight source to emit light through the pixel unit, in addition, the display module 11 may also be an organic light emitting display module, the organic light emitting display module includes an organic light emitting display panel and a driving chip bound with the organic light emitting display panel, and the organic light emitting display module includes organic light emitting elements arranged in an array and can be driven by an electrical signal input by the driving chip. The light emitting side of the display module 11 can be further provided with a touch control functional layer 16, and the touch control functional layer 16 can realize touch control of a user on the display module 11, so that the user can operate the display module 11 conveniently and input control instructions. The touch functional layer 16 is provided with the protection apron 14 far away from one side of display module assembly 11, and the protection apron 14 is used for protecting touch functional layer 16 and display module assembly 11, prevents the collision damage of touch functional layer 16 and display module assembly 11, improves touch display module assembly 1's life-span. Optionally, the touch functional layer 16 and the protective cover plate 14 are attached by the optical adhesive 12 or the water adhesive, so that the light transmittance of the optical adhesive or the water adhesive is high, the light emitting of the display module 11 is not affected, the bonding strength is good, the bonding strength of the touch functional layer 16 and the protective cover plate 14 is enhanced, the heat resistance, the humidity resistance and the photo aging resistance are high, and the service life of the touch display module 1 is convenient to improve. Illustratively, the protective cover 14 may be a light transmissive material such as glass. A colored ink layer 13 is arranged between the touch functional layer 16 and the protective cover plate 14, and the colored ink layer 13 can shield frame materials at the edges of the display module 11 and the touch functional layer 16, so that the touch display module 1 is attractive in appearance. Alternatively, the color of the colored ink layer 13 may be black, white or colored, and the color of the colored ink layer 13 may be set arbitrarily according to the user's requirement, and it should be noted that when the color of the colored ink layer 13 is colored, the color of the colored ink layer 13 may be set to one of the colors instead of simultaneously setting the colors of the colored ink layer 13 to a plurality of colors, so as to facilitate the color balance between the colored ink layer 13 and the display area 21. Illustratively, the present embodiment may set the color of the colored ink layer 13 to black, so as to achieve an integral black display effect of the colored ink layer 13 and the display area 21.
Referring to fig. 3, the touch display module includes a display area 21 and a non-display area 22 surrounding the display area 21, and the colored ink layer 13 is disposed on the non-display area 22 and surrounding the display area 21. The touch display module further includes a negative refraction layer 15, where the negative refraction layer 15 is disposed in the non-display area 22 and also disposed around the display area 21, as shown in fig. 3, in a direction x in which the non-display area 22 points to the display area 21, a front projection of the negative refraction layer 15 on the display module exceeds a front projection of the colored ink layer 13 on the display module near a first edge L3 of the display area 21, so as to prevent external light reflected by the first edge L3 of the colored ink layer 13 from exiting from a light-emitting side of the display module. Because the colored ink layer 13 absorbs light energy strongly, the brightness of the external light reflected from the colored ink layer 13 is lower than that of the external light directly reflected by the display module 11, so that the external light reflected by the first edge L3 of the colored ink layer 13 needs to be prevented from exiting from the light-emitting side of the display module as much as possible, and from being seen by human eyes, thereby avoiding dark shadows generated between the external light with large brightness difference and affecting the visual effect of the user. In the direction x, the front projection of the negative refraction layer 15 on the display module exceeds the front projection of the first edge L3 on the display module, or exceeds the front projection of the first edge L3 on the display module. The negative refractive layer 15 has a negative refractive characteristic, which is a characteristic corresponding to a positive refractive characteristic, with reference to fig. 5, fig. 5 is a refractive effect diagram of a positive refractive characteristic provided by an embodiment of the present invention, fig. 6 is a refractive effect diagram of a negative refractive characteristic provided by an embodiment of the present invention, with reference to fig. 5, the positive refractive characteristic refers to that when an incident light ray λ1 enters a positive refractive index material, an outgoing light ray and an incident light ray are respectively located at two sides of a normal line of the positive refractive index material, and with reference to fig. 6, the negative refractive characteristic refers to that when an incident light ray λ2 enters a negative refractive index material, an outgoing light ray and an incident light ray are respectively located at the same side of the normal line of the negative refractive index material. The negative refractive layer in this embodiment changes the propagation direction of the external light by using its negative refractive index characteristic, reflects the external light to the non-light-emitting side, and prevents the external light reflected by the edge of the colored ink layer near the display area from exiting from the light-emitting side of the display module.
Alternatively, the negative refractive layer may be a photonic crystal having a negative refractive index. Photonic crystals refer to artificial periodic dielectric structures having photonic band gap characteristics, which means that waves in a certain frequency range cannot propagate in the periodic structure, and the photonic crystals have a certain selectivity for propagating light. In this embodiment, the negative refractive layer is a photonic crystal, the photonic crystal is a microstructure with dielectric constant periodically changing along with space, and the constituent material of the photonic crystal may be at least one of inorganic or organic matters such as silicon, titanium dioxide, niobium pentoxide, silicon monoxide, polyethylene acid, polystyrene, etc., and the photonic crystal may be made of titanium oxide, for example. From the above, the photonic crystal has a periodic structure to select a light of a certain light wave band for transmission. Specifically, the periodic structure of the photonic crystal has a period length that is half of the wavelength of the transmissible light wave band, and in order to enable human eye visible light in the wave band of 400nm to 800nm to propagate in the photonic crystal, optionally, in this embodiment, the photonic crystal has a periodic structure, and the period length of the periodic structure may be 200nm to 400nm. In this embodiment, the photonic crystal having a period length of 200nm to 400nm has a negative refractive index characteristic for visible light of the human eye in a wavelength band of 400nm to 800 nm.

In this embodiment, the thickness of the negative refraction layer 15 is the same as the thickness of the colored ink layer 13, and the edges of the negative refraction layer 15 contacting the colored ink layer 13 are completely aligned, i.e. the side wall of the negative refraction layer 15 far from the outer edge of the display area 21 is completely matched with the side wall of the first edge L3 of the colored ink layer 13, which can prevent the external light reflected by the first edge L3 of the colored ink layer 13 from exiting from the light-emitting side of the display module 11, and can improve the aesthetics of the arrangement of the negative refraction layer 15 and the colored ink layer 13.
