Detailed Description
(example 1)
Referring to fig. 1 to 3 and fig. 6, the display backplane of the full-color scanning display device of the present embodiment includes a substrate 1 made of a silicon substrate and tapered slots etched on the silicon substrate and having a trapezoidal cross section with a wide top and a narrow bottom, where the tapered slots are used as a cavity 2 for encapsulating phosphor; silica gel is sealed in each cavity 2; as shown in fig. 2, every four adjacent cavities 2 are used as a display pixel, and respectively encapsulate silica gel containing red phosphor, silica gel containing yellow phosphor, silica gel containing green phosphor, and silica gel not containing phosphor for reflecting blue light. For better reflection, a plating layer 23 is provided on the inner wall of each cavity 2. The plating layer 23 is the most suitable choice for aluminum plating, and the cost is controllable. Each cavity is of uniform size and shape, and the size is determined by the display pixel requirements, for example, a 400um x 400um pixel frame can be formed by four 200um x 200um cavities 2.
The manufacturing method comprises the following steps:
the method comprises the following steps: preparing a silicon substrate; the silicon substrate adopts an SOI wafer or a monocrystalline silicon wafer;
step two: covering a layer of silicon nitride or silicon oxide film on the surface of a silicon substrate by adopting a chemical deposition CVD method, etching the silicon oxide or silicon nitride protective film by adopting a wet method or a plasma dry etching method, and etching the silicon oxide or silicon nitride protective film into a trapezoidal unit groove with a wide upper part and a narrow lower part along 100 surfaces of silicon by adopting alkaline solvent TMAH or KOH wet etching; of course, the inverted triangular cell slots 21 shown in FIG. 6 may also be etched;
step three: the inner wall of each silicon cup is plated with aluminum or other metal or inorganic substance to form a plating layer 23, and then the fluorescent powder and the silica gel 3 are packaged in the silicon cup. With four adjacent cavities 2 as a unit, silica gel containing red phosphor, silica gel containing yellow phosphor, green phosphor containing silica gel, and silica gel not containing phosphor for reflecting blue light are respectively packaged in the four cavities 2 in a dispensing manner.
This structure of this embodiment can also be obtained by nano-printing on a plastic substrate with a special (according to the desired pattern) roller, such as the inverted triangular unit cell 21 of fig. 6. Or the required cavity is etched on the glass substrate by using buffered hydrofluoric acid BHF and hydrofluoric acid HF, but the etching of the hydrofluoric acid is isotropic, so that the cross section of the cavity is arc-shaped unit grooves arranged at intervals transversely and longitudinally (as shown in FIG. 7), or the cross section of the cavity is a semicircular or arc-shaped long groove arranged at intervals transversely and parallelly. By adopting the structure of the embodiment, since the cavity is in a trapezoid shape with a large upper part and a small lower part (the included angle between the inclined plane and the horizontal plane is generally 72 degrees), the phosphor is easy to deposit when being spotted, that is, the packaging process of the phosphor is easy to operate, but the requirement on the etching process is high if a very high pixel is required due to a large opening.
When full-color scanning display is performed, blue laser is irradiated onto the display substrate of the present embodiment, a desired color can be mixed by controlling the power and the dwell time of the blue laser, and a stereoscopic display effect can be obtained when the blue laser is rotated.
(example 2)
Referring to fig. 4 and 5, the difference from embodiment 1 is that: the cavity 2 is shaped by adopting transverse parallel spaced straight grooves 23, etching is carried out along the 110 faces of silicon, and silica gel containing red fluorescent powder, silica gel containing yellow fluorescent powder, silica gel containing green fluorescent powder and pure silicon which is used for reflecting blue light and does not contain fluorescent powder are respectively packaged in four adjacent straight grooves 23. The benefits of this are: according to the structure of silicon atoms, grooves with the same size can be etched along the 110 surfaces, so that the advantages that the opening can be smaller, the pixel can be very high, and the display bottom plate can be made smaller, thereby being convenient for being used in occasions needing smaller volume.
The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
