Problems solved by technology

[0004] However, due to cost constraints, currently Mini-LED can only achieve the size of 10mm*10mm, and the large screen that best embodies Mini-LED display technology is difficult to be popularized and applied due to cost or yield factors.
[0005] Based on this, this application proposes a Mini-LED display splicing display driving system and a driving display method to solve the problem of Mini-LED large-screen display

Embodiment 1

[0041] figure 1 The structural schematic diagram of the Mini-LED display splicing display drive system provided for the embodiment of this application includes: a storage module 1, a control module 2 and a Mini-LED display module 3, the storage module 1 is used to provide display data, and the The control module 2 is used to process the display data into a display signal and send it to the Mini-LED display module 3. The Mini-LED display module 3 receives the display signal to control the display of the Mini-LED display. The LED display module 3 is spliced ​​by two or three Mini-LED display units. Specifically, the display unit has a resolution of 135*120, the size of the LED chips is 100 microns, and the spacing between the LED chips is 680 Micron Mini-LED display.

[0042] In this embodiment, the storage module 1 can be a memory card, preferably a micro SD card. This embodiment uses a micro SD card, which is more conducive to saving space. Specifically, the storage module 1...

Embodiment 2

[0081] This embodiment further proposes a driving display method for splicing display of two, three, six and eight Mini-LED screens, such as Image 6 As shown, the steps are as follows:

[0082] S100. The display data processing unit reads the display data from the SD card, and transmits the read data and address to the cache unit.

[0083] In this embodiment, the reading of display data is controlled according to SWITCH, and the SPI working mode (SD_CS signal is active at low level) is enabled for signal gating. The flow diagram is shown in image 3 and Figure 4 shown. The main logic is to use the state machine to perform each working state in SPI mode, including initialization (STATE_spi_init), empty state (STATE_spi_idle), transmission (STATE_spi_tx), transmission 1 (STATE_spi_tx1) and transmission 2 (STATE_spi_tx2). In the sending state, each rising edge of the clock accepts 1 bit data, and at least 8 clocks are required to transmit 8 bit data.

[0084] Secondly, acco...

Abstract

The embodiment of the invention discloses a Mini- LED display screen splicing display driving system and a Mini -LED display screen splicing display driving method, and the system reads and processes display data in a storage module, transmits a signal to a Mini -LED driving chip, and finally enables the display data to be displayed on a plurality of Mini- LED display screens in a splicing manner. According to the method, a display data processing unit reads display data from a storage module and transmits the read data and addresses to a cache unit, and an RGB data processing unit receives data output by the cache unit, processes the data and transmits data streams, latch signals and clock signals. And the driving unit receives the data stream, the latch signal and the clock signal output by the RGB data processing unit, processes the data stream, the latch signal and the clock signal, generates a clock and a data read-in signal of a Mini- LED screen driving chip, and finally enables display data to be displayed on a plurality of Mini- LED display screens in a spliced manner, thereby solving the problem of large-screen display of Mini- LEDs.

Description

technical field [0001] Embodiments of the present invention relate to LED display technology, and in particular to a Mini-LED display splicing display driving system and a driving display method. Background technique [0002] Mini-LED is a new type of LED display technology derived from small-pitch LEDs, also known as submillimeter light-emitting diodes. Its grain size is about 50 to 200 microns, which is between traditional LED and Micro LED, and has great potential for industry development. [0003] The Mini-LED backlight adopts the direct LED backlight method, which greatly reduces the size of the LED grain. It has the advantages of adjustable regional brightness, high color rendering, and high contrast. At the same time, its thinner thickness, more power-saving, and bendable characteristics also make its application more flexible. [0004] However, due to cost constraints, currently Mini-LED can only achieve a size of 10mm*10mm, and the large screen that best embodies...
