Solution Overview
Problem
The existing phase development circuit devices face challenges in driving high-resolution electro-optical panels due to insufficient driving capability and heat generation issues, making it difficult to increase the number of outputs effectively.
Innovation Solution
The implementation of multiple phase development circuit devices, where each circuit device drives alternate data line groups of the electro-optical panel, with separate encapsulation to facilitate heat dissipation and reduce gradation differences in output voltages, thereby improving display quality.

Engineering Contradiction Analysis
1Productivity
If the number of outputs of the phase development circuit device is increased to drive high-resolution panels, then the driving capability is improved, but heat generation increases and becomes difficult to manage
Solution Approach 1:
The phase development circuit device is divided into multiple independent circuit devices (first circuit device and second circuit device). Each device drives a separate data line block, distributing the heat generation across multiple devices rather than concentrating it in one device. This segmentation allows high-resolution panel driving while managing heat through spatial distribution.
2Temperature
If multiple phase development circuit devices are used to increase driving capability, then heat dissipation becomes easier, but gradation differences in output voltages occur between devices
Solution Approach 1:
Data line blocks driven by different circuit devices are arranged in specific positions on the panel. By controlling which data line blocks are driven by which circuit device and their spatial arrangement, the patent optimizes local heat dissipation conditions while minimizing visible gradation differences through strategic positioning of data line blocks.
3Device complexity
If a single circuit device drives all data lines, then the device structure is simple, but the driving capability for high-resolution panels is insufficient
Solution Approach 1:
The data lines are divided into multiple data line blocks (first data line block to n-th data line block), with each block driven by a separate circuit device. This segmentation enables high-resolution panel driving capability while keeping each individual circuit device relatively simple in structure.
Solution Approach 2:
The patent introduces a new dimension of organization by arranging data line blocks in spatial positions on the panel and assigning different circuit devices to different spatial regions. This spatial-dimension approach allows scaling to high resolutions without proportionally increasing the complexity of each circuit device.

AI summary
An electro-optical device includes an electro-optical panel including first to n-th (n is an integer of 2 or greater) data line blocks with each data line block including a first data line group and a second data line group, a first circuit device, and a second circuit device. The first circuit device drives, in an i-th phase of phase development drive, the first data line group of an i-th data line block of the first to n-th data line blocks, and the second circuit device drives, in the i-th phase of the phase development drive, the second data line group of the i-th data line block of the first to n-th data line blocks.
