[0002] With the rapid development of display technology, display panels are being used more and more widely in consumer electronics, industrial control and other fields.
[0003] In existing technologies, traditional display panels typically require external driver chips to control pixels. However, these external driver chips usually need to be placed around the perimeter of the display panel, which prevents the panel bezels from being made narrow, affecting the product's aesthetics and screen-to-body ratio. Furthermore, dedicated driver chips need to be purchased separately, resulting in a long procurement cycle and increased material costs. Additionally, the bonding process between the driver chip and the panel increases manufacturing costs. Utility Model Content

[0025] Please see Figures 1 to 2 A narrow bezel display panel according to an embodiment of the present invention includes:
[0026] Display unit array 10, which includes a plurality of OLED structures 11.
[0027] The driving module array 20 includes a plurality of driving module structures 21 correspondingly disposed at the bottom of the OLED structure 11 and a project signal layer 22 disposed at the bottom of the driving module structures 21 for connecting external input LVDS signals and external power supply. The driving module structure 21 includes an LVDS receiver 211 for receiving external input LVDS signals, a decoder 212 communicatively connected to the LVDS receiver 211 for decoding external input LVDS signals, a data storage 213 communicatively connected to the decoder 212 for storing decoded display data, a PWM generator 214 signal-connected to the data storage 213 for converting display data into PWM drive signals, and an LED driving circuit 215 communicatively connected to the PWM generator 214 for driving the OLED structure 11.
[0028] Substrate 30 is disposed at the bottom of the project signal layer 22.
[0029] Understandably, by setting the driving module structure 21 at the bottom of the OLED structure 11, the wiring space requirement of traditional driving chips around the panel is eliminated, the panel bezel width can be narrowed, the product aesthetics are improved and the screen ratio is optimized. At the same time, the purchase of dedicated chips can be eliminated, the procurement cycle is avoided, the material cost is reduced, and the bonding process between the driving chip and the panel is reduced, further reducing the manufacturing cost.
[0030] Furthermore, the specific model of the LVDS receiver 211 is DS90LV047A, the specific model of the decoder 212 is iCE40UP5K, the specific model of the data memory 213 is 23LC1024, the specific model of the PWM generator 214 is PCA9685, and the specific model of the LED driver circuit 215 is ALED1642GW.
[0031] Furthermore, the driver module structure 21 also includes an address memory 216 that is communicatively connected to the decoder 212 for storing decoded address information.
[0032] Furthermore, the driving module structure 21 also includes a pre-stored address unit 217 which is communicatively connected to the address memory 216 for storing fixed addresses corresponding to each driving module structure 21.
[0033] Furthermore, the driving module structure 21 also includes a comparator 218 for comparing the address information of the address memory 217 with the address information of the pre-stored addresser 217. The comparator 218 is disposed between the address memory 216 and the pre-stored addresser 217, and the comparator 218 is signal-connected to the pre-stored addresser 217, the address memory 216 and the data memory 213 respectively.
[0034] Furthermore, the specific model of the address memory 216 is MR25H40CDF, the specific model of the pre-stored addresser 217 is DS28E01G+, and the specific model of the comparator 218 is TLV3201.
[0035] Understandably, the project signal layer 22 is powered on and receives externally input LVDS signals, and simultaneously outputs the externally input LVDS signals to each of the LVDS receivers 211. In the same drive module structure 21, the LVDS receivers output the received LVDS signals to the decoder 212. The decoder 212 decodes the externally input LVDS signals into display data and address information, and outputs them to the data memory 213 and the address memory 216 for storage, respectively. The address memory 216 outputs the decoded address information to the comparator 218. The comparator 218 compares the decoded address information with the corresponding fixed address pre-stored in the pre-stored addresser 217.
[0036] It should be noted that, within the same driver module structure 21, if the decoded address information is not the same as the corresponding fixed address stored in the pre-stored addresser 217, the process will terminate.
[0037] It should be noted that, within the same driving module structure 21, if the decoded address information is the same as the corresponding fixed address pre-stored in the pre-stored addresser 217, then the comparator 218 controls the data memory 213 to output the decoded display data to the PWM generator 214. The PWM generator 214 converts the decoded display data into a PWM drive signal and outputs it to the LED drive circuit 215. The LED drive circuit 215 drives the OLED structure 11 according to the input PWM drive signal.
[0038] Furthermore, a pad array 222 is provided on the top of the project signal layer 22 on the side away from the drive module structure 21. The pad array 222 includes a pad structure 223 and an FPC structure 224 for connecting external input LVDS signals and external power supply.
[0039] On the other hand, this utility model also provides a display module, including the aforementioned narrow bezel display panel.
[0040] In summary, the narrow bezel display panel and display module in the above embodiments of this utility model eliminate the wiring space requirement of traditional driver chips around the panel by setting the driving module structure at the bottom of the OLED structure, which allows the panel bezel width to be narrowed, increases product aesthetics and optimizes screen ratio. At the same time, it can save the purchase of dedicated chips, avoid procurement cycle, reduce material costs, and further reduce manufacturing costs by reducing the bonding process between driver chips and panel.
