Publication number: 20230171988Abstract: An electronic device may have a display such as an organic light-emitting diode display. The organic light-emitting diode (OLED) display may have an array of organic light-emitting diode pixels that each have OLED layers interposed between a cathode and an anode. A first passivation layer, a first planarization layer, and a second passivation layer may be formed over the cathode. The first and second passivation layers may be formed from inorganic material. A second planarization layer may be formed over the second passivation layer between the second passivation layer and a polarizer. The second planarization layer may planarize the polarizer at the edges of the active area of the display where the polarizer would otherwise have a steep taper. Planarizing the polarizer in this way mitigates undesirable secondary reflections off of the polarizer. The first and second planarization layers may be formed from organic material.Type: ApplicationFiled: October 18, 2022Publication date: June 1, 2023Inventors: Prashant Mandlik, Bhadrinarayana Lalgudi Visweswaran, Ankit Mahajan, Chia-Hao Chang, Christopher E Glazowski, David L Wei, Hui Lu, Takahide Ishii, Themistoklis Afentakis, Han Liu, Cheng-Chih Hsieh, Asli Sirman, Shih Chang Chang, Ko-Wei Chen, Shang-Chih Lin, Tsung-Ting Tsai, Jae Won Choi, Abbas Jamshidi Roudbari, Ting-Kuo Chang, Jean-Pierre S Guillou

Publication number: 20230080552Abstract: An organic light-emitting diode (OLED) display may have an array of pixels that each have OLED layers interposed between a cathode and an anode. The display may also include a planarization layer that is deposited using inkjet printing. To mitigate the need for dam structures to prevent overflow of the planarization layer during inkjet printing, capillary-flow-inducing structures may be included in the inactive area of the display. The topology of the capillary-flow-inducing structures may be propagated to a passivation layer such that an upper surface of the passivation layer has a similar topology as the capillary-flow-inducing structures. The planarization layer therefore undergoes capillary flow when deposited on the upper surface of the passivation layer. The capillary-flow-inducing structures may be formed from dots, rectangular strips, or trapezoidal strips. The capillary-flow-inducing structures may be formed from the same material as spacers in the active area or using another layer in the display.Type: ApplicationFiled: May 27, 2022Publication date: March 16, 2023Inventors: Kuan-Yi Lee, Takahide Ishii, Prashant Mandlik, Chih-Lei Chen, Bhadrinarayana Lalgudi Visweswaran, Ankit Mahajan

Publication number: 20220237162Abstract: Methods for cardinality estimation feedback loops in query processing are performed by systems and devices. A query host executes queries against data sources via an engine based on estimated cardinalities, and query monitors generate event signals during and at completion of execution. Event signals include indicia of actual data cardinality, runtime statistics, and query parameters in query plans, and are routed to analyzers of a feedback optimizer where event signal information is analyzed. The feedback optimizer utilizes analysis results to generate change recommendations as feedback for later executions of the queries, or similar queries, performed by a query optimizer of the query host. The query host stores change recommendations, and subsequent queries are monitored for the same or similar queries to which change recommendations are applied to query plans for execution and observance by the query monitors. Change recommendations are optionally viewed and selected via a user interface.Type: ApplicationFiled: April 19, 2022Publication date: July 28, 2022Inventors: Pedro M. Lopes, Vasileios Papadimos, Joel L. Redman, JR., Gjorgji Gjeorgjievski, Joseph I. Sack, In-Jerng Choe, Ankit Mahajan, Nan Xing, Alexey Eksarevskiy, Chandrashekhar Kadiam

Publication number: 20220189790Abstract: A method includes placing an electronic device on a pliable mating surface on a major surface of a mold such that at least one contact pad on the electronic device presses against the pliable mating surface. The pliable mating surface is on a microstructure in an arrangement of microstructures on the major surface of the mold. A liquid encapsulant material is applied over the electronic device and the major surface of the mold, and then hardened to form a carrier for the electronic device. The mold and the carrier are separated such that the microstructures on the mold form a corresponding arrangement of microchannels in the carrier, and at least one contact pad on the electronic device is exposed in a microchannel in the arrangement of microchannels. A conductive particle-containing liquid is deposited in the microchannel, which directly contacts the contact pad exposed in the microchannel.Type: ApplicationFiled: April 14, 2020Publication date: June 16, 2022Inventors: Ankit Mahajan, Saagar A.
