The composition of buffer layer would be played a key role to affect the electrical performance and the reliability of the selfaligned top-gate a-IGZO TFTs. In this work, the threshold voltage shift (ΔVth) of the device could be less than ±1V under positive and negative bias thermal illumination stress.

The RGB micro‐LED display has been demonstrated to withstand mechanical strain during out‐of‐plane periodically deformation. In this work, the high pixel density (>139‐PPI) and high strain tolerance of circuits were achieved by utilizing the novel design of the island‐bridge structure under the compact pixel arrangement. Light absorbent was adopted into a stretchable display to reduce ambient back light and ambient reflection for the dark mode of a panel

A capillary electrophoretic (CE) method coupled with the use of 1-ethyl-3-methylimidazolium tetrafluoroborate (1E-3MI-TFB) ionic liquid as background electrolyte (BGE) has been developed for the simultaneous separation of nine tricyclic antidepressants, viz. amitriptyline (Ami), clomipramine (Clo), desipramine (Des), fluphenazine (Flu), imipramine (Imi), nortriptyline (Nor), promazine (Pro), thioridazine (Thi) and trimipramine (Tri). Resolution of TCAs with similar molecular structures and pK a values was accomplished by minute manipulation of the electrophoretic velocities of TCAs via reversed electroosmotic flow (EOF) generated by adsorption of 1E-3MI cations onto the capillary wall. The optimal separation was obtained with a 50 mM 1E-3MI-TFB as the sole BGE at pH 3. Symmetric peaks with efficiencies up to 2.4´10 5 plates/m were achieved. RSD values on migration times and peak areas were in the ranges of 0.63-0.95% and 3.41-6.34% (n = 4), respectively. The role of different alkyl groups on the imidazolium cations was also investigated.
