技術說明

【中文發明名稱】 QLED顯示面板之串擾改善方法以及QLED顯示面板 【英文發明名稱】 Method for canceling crosstalk of QLED display panel and QLED display panel 【中文】 本發明主要揭示一種QLED顯示面板之串擾改善方法，其應用於一QLED顯示器之中，其中該QLED顯示器包括：一QLED顯示面板、一列驅動單元、一行驅動單元、以及一控制單元。並且，該QLED顯示面板包含M條陽極導線、N條陰極導線、以及M×N個QLED元件。在應用本發明之串擾改善方法的情況下，該控制單元控制該行驅動單元對被選定的至少一個QLED元件提供一正向偏壓，同時該控制單元控制該列驅動單元對其它未被選定的多個QLED元件提供一反向偏壓。如此設計，在被選定的至少一個QLED元件發光時，其它QLED元件便不會同時發出微弱光而形成顯示串擾。 The present invention discloses a method for application in a QLED display device so as to cancel optical crosstalk occurring in a QLED display panel of the QLED display device. The QLED display device comprises the QLED display panel, a low driver unit, a column driver unit, and a control unit, wherein the QLED display panel comprises M number of anode wires, N number of cathode wires, and MxN number of QLED elements. In case of the method is implemented in the QLED display device, the control unit controls the column driver unit to supply a positive bias voltage to at least one QLED element that is addressingly selected. In the meantime, the control unit also controls the low driver unit to supply a reverse bias voltages to each of the QLED elements that are not selected. In such case, when the addressingly-selected QLED element achieves a light emission normally, each of the QLED elements that are not selected is reversely biased for failing to produce an optical crosstalk.
