Embodiment
With reference to the accompanying drawings the present invention is described more fully, exemplary embodiment of the present invention wherein is described.
Shown in Fig. 1 (a), led chip 1 of the present invention is the high brightness LED chip take gallium nitride as material, i.e. gallium nitrate based high brightness LED chip.According to a preferred embodiment of the present invention, the physical dimension of described led chip is 5mm * 5mm.Need to prove, the present invention is not limited to this, and those skilled in the art can arrange the size of suitable led chip as required.
Shown in Fig. 1 (b), by to the amplification at the left little angle 10 of the led chip among Fig. 1 (a) and right little angle 11 as can be known, have the LED matrix in the described led chip 1, preferred, the LED matrix is 128 * 128 LED matrix.Equally, it will be understood by those skilled in the art that 128 * 128 LED matrix is an example of the present invention, the present invention is not limited to this, more than 128 * and LED matrix more than 128 is equally applicable to the present invention.The row of 128 * 128 LED matrix is connected with conductive material respectively with row.Described conductive material is and is arranged in led chip 1 solder joint all around.
Because the present invention directly is welded to led chip on the asic chip by the solder joint on the led chip, in order to guarantee that led chip firmly is welded on the asic chip, just need to make the solder joint on the led chip as far as possible large.Yet the present invention is the display chip that will make for glasses, and this just requires the volume of chip smaller.For this reason, the design of uniqueness of the present invention the set-up mode of the solder joint on the led chip.Shown in Fig. 1 (b), the present invention is provided with solder joint around led chip 1, and staggers mutually in the position of the solder joint of the solder joint of a side of described led chip 1 and opposite side.In particular, the LED that the solder joint in led chip 1 left side only connects even number is capable, and the LED that the solder joint on led chip right side only connects odd-numbered line is capable.Similarly arrange for the solder joint that connects the LED row.So just in the situation that the volume of chip own is smaller, compare with the both sides that solder joint only are arranged on led chip 1, the volume of solder joint is doubled.
Fig. 2 shows asic chip of the present invention, and this asic chip is the common asic chip based on the I industrywide standard, can at ASICXI concrete circuit be set according to actual needs, and its concrete structure does not repeat them here.At described asic chip the pad corresponding with led chip is set.The present invention is more bigger than led chip, concrete with the size design of asic chip, and the size of described asic chip is 6mm * 5mm.As seen from Figure 2, the present invention is provided with a plurality of interface 1-18 at asic chip, wherein, interface 1-4,10-12 and 18 is power interface, interface 5-9,13-17 are the HDMI interface, or other digital picture signal interfaces.
Fig. 3 shows the schematic diagram that led chip and asic chip are welded as a whole.As shown in Figure 3, use BGA (Ball Grid Array) packaged type that led chip 100 and asic chip 200 are welded together, asic chip receives the signal that is sent by the HDMI digital interface, control LED lights, show thereby finish image, form round-the-clock applicable high brightness one chip LED display chip proposed by the invention.
Fig. 4 shows an Application Example of round-the-clock applicable high brightness one chip LED display chip of the present invention.As shown in Figure 4, by routing 41 with the power supply on the ASIC and HDMI interface encapsulation on the IC of standard enclosed seat 43, the representative of 42 among Fig. 4 is shielded display surface by the highlighted LED that led chip forms.After on the IC enclosed seat 43 that LED display chip routing is encapsulated into standard, just formed the one chip LED display chip 44 after the encapsulation, one chip LED display chip 44 after this encapsulation is added lens, can form the round-the-clock one chip display screen 45 of high brightness.
By above analysis as can be known, round-the-clock applicable high brightness one chip LED display chip provided by the present invention is comprised of high brightness LED chip and ASIC, wherein, described high brightness LED chip comprises 128 * 128 led array, around described high brightness LED chip a plurality of solder joints are set, described solder joint connects the row or column of described led array; The solder joint corresponding with the phase of solder joint that arranges all around of described high brightness LED chip is set around described asic chip, by the BGA packaged type described led chip and asic chip are directly welded together, form described round-the-clock applicable high brightness one chip LED display chip.
In addition, can described high brightness one chip LED display chip be encapsulated on the IC enclosed seat of standard by routing, to form the one chip LED display chip after encapsulating, the one chip LED display chip after the described encapsulation is added lens, can form the round-the-clock one chip display screen of high brightness.
The present invention is by being welded direct to led chip on the asic chip, provide volume little, the LED display chip that brightness is high, this LED display chip is owing to having advantages of that volume is little, use so have widely, for example, can be installed on the spectacle frame, use to supply with outdoor user, and, LED display chip of the present invention is because volume is little, so power consumption is low especially.In addition, LED display chip provided by the present invention has adopted gallium nitrate based high brightness LED chip, and brightness is high especially, so even the strong place of sunlight out of doors, the user also can clearly watch the content on the LED display chip.In addition, LED display chip of the present invention takes full advantage of the advantage of asic chip, and integrated numerous power supply and HDMI interface is convenient to be connected with other electronic equipment.
In a word, the present invention compares with existing LED display, has that volume is little, brightness is high, low in energy consumption, temperature applicable range is wide, and has advantages of a plurality of power supplys and HDMI interface, has higher actual application value.
Above content is preferred embodiment of the present invention only, for those of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, and this description should not be construed as limitation of the present invention.
