Problems solved by technology
[0003] As the demand for display size increases in the market, the manufacturing process of a single substrate display is becoming more and more difficult for LCD or OLED. Not only is the yield rate extremely low, but the production cost is also extremely expensive.
Conventional OLED large-size display screens are spliced with multiple OLED display modules, and each corresponding OLED display must be connected to a driver chip, so its production cost is quite expensive

Embodiment Construction
[0022] The basic idea of the present invention is that each row of OLED displays is connected to the controller through a row driver, and each column of OLED displays is connected to the controller through a column driver, so as to realize a large-size display screen structure with M rows and N columns.
[0023] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0024] see figure 1 , is a structural schematic diagram of the large-size display screen of the present invention. figure 1 Disclosed is a spliced large-size display screen located on the same plane, the specific realization of which is as follows: a plurality of organic light-emitting diode (OLED) displays are regularly arranged in M rows and N columns, and each OLED display does not need to be individually bound ...

The invention relates to the technology of organic light emitting diode and specifically discloses a large size display screen. The large size display screen is spliced by M rows * N columns of organic light emitting diode (OLED) displays, and each OLED display is not singly bound with a driving chip necessarily, wherein each row of OLED displays is connected with a row drive in parallel or connected with a plurality of row drives in parallel in groups; each column of OLED displays is connected with a column drive in parallel or connected with a plurality of column drives in parallel in groups; and all row drives and all column drives are connected to a controller so as to drive the large size display screen to display according t a preset demand. The large size display screen of the invention is spliced by a plurality of OLED displays and each OLED display is not singly bound with the driving chip necessarily, thereby greatly simplifying production procedures, reducing a manufacturing cost and facilitating market generalization.
Description
technical field [0001] The invention relates to an organic light emitting diode display technology, in particular to a spliced OLED large-size display screen. Background technique [0002] As a new type of display product, organic light emitting diode (OLED) display has many advantages, such as active light emission, fast response speed, wide viewing angle, and flexible display, compared with the current mainstream flat-panel product liquid crystal display LCD. With strong competitiveness, it is very likely to become the mainstream product of the next generation of flat panel displays. [0003] As the demand for display size increases in the market, it is becoming more and more difficult to manufacture a single substrate display process for either LCD or OLED. Not only is the yield rate extremely low, but the production cost is also extremely expensive. A conventional large-size OLED display is spliced by multiple OLED display modules, and each corresponding OLED displa...
